Mac Pro & Boot Camp
OK. Here's how I got XP running on my stock 2.66 Mac Pro. I'm writing this from Internet Explorer on XP sp2
1. Download boot camp here
2. Run Boot Camp & follow instructions (soooo easy)
3. I partitioned my XP drive to 20GB. You will want to keep it under 32GB if you want to format it FAT instead of NTFS. This way you can write to the drive from OSX
4. Burn your drivers CD. Mine did NOT work in XP. That's why I'm writing this.
5. Insert your XP CD and install
6. Once windows is installed, you can try to install your boot camp drivers, but mind said my hardwarre was incompatible. I had 640x480 in blorious 4bit colour! No networking!
7. Time eboot back to OSX and download some drivers.
8. My mac came with the stock 7300 so I downloaded the XP drivers from here
9. I couldn't find any info on the manufactureer of the network cards on the mac, so I took an educated guess and downloaded the intel PRO/1000 drivers from here
10. save these drivers to your FAT windows drive or a usb key, which should work in XP
11. Back in XP install the nvidia driver, my version was 91.31
12 It didn't work straight away, but windows found new hardware "pci bridge" and asked me to restart. After a restart, I think I had to intsall the drivers again, but it worked. Now I have 2 monitors running at 1280x960 in dualview!
13. Next I installed the intel network driver PRO2KXP.exe
14 Towards the end of the installation a little window popped up to tell me that Local area comnnection 3 was unplugged. This was the second etherned port that I'm not using. I was on the net straight away!
I hope this helps anyone with shiny new Mac Pros run their windows only apps at full speed. For me, it's Maya. I'll just wait patiently until Autodesk bring out a universal binary on Maya 8.

I have installed all of them and my system is fully functional now, but I still get the yellow ! marks for PCI Express x4 Fort 2-7.
If you ask me, the whole "you can't use a PC graphics card in your Mac Pro" is a whole bunch of baloney. I hope someone figures out how to get those PC graphics card to communicate with the BIOS-compatible EFI chips because there are zero reasons why a Mac card can work in Windows and why a PC card can't work it's magic on OS X...unless of course EFI sucks more than BIOS...and we all know this isn't true.

My guess is that it comes down to card firmware.
I would bet (this is pure speculation) that if you flashed a PC Radeon X1900 with a Mac Radeon's firmware, you'd get... a Mac Radeon.
And drivers are still a huge issue, if you care at all about Coreimage and OpenGL accelleration in OS X.
Some say it has something to do with the fact that the Mac cards have a 128k ROM on them...but why would that firmware work on both Mac and PC and why would the traditional 64k ROM from PC cards *only* work on PCs.
Apple is still up to old tricks. At least the CPU on the Mac Pro is socketable. But I bet if Apple had it their way, the CPU would be soldered on.
It's still inconceivable that a Mac gfx card works under Windows (with the correct drivers) and that a PC gfx card does not work under OS X. If OS X has the drivers for the card...it should just work. If *anything* EFI should be able to handle any BIOS-only cards or EFI-cards...nobody should be expecting the opposite (the opposite being a card, needing EFI, to work on Windows which boots using the emulated BIOS calls.)

The video cards need a efi bios to post. So a bios only one may fail to post. After boot up the os drivers take over.
Somebody just used a PC 7800GTX in a Mac Pro over at the Macrumors forums, wasn't fullspeed since he couldn't figure out how to get extra power to it, but proves it can be done. Probably won't work with Mac OS X though, only Windows.
If so, you could:
1) Buy PC OMGWTFBBQINSANE graphics card
2) Get a Mac Pro with 7300GT.
3) Toss the 7300GT in a x8 or x4 slot, and the other card in the x16 slot.
4) Have decent OS X graphics, and great Game OS graphics.
