<strong>Can I safely put an AGP 4x card in a 2x slot? Will the drivers and hardware work correctly? I can't seem to find any hard evidence either way. Thanks.</strong><hr></blockquote>
Every AGP card I know is backwards compatible; a 4x can be used in a 2x and 1x.
For regards to drivers, is it a PC Graphics card (generic) and needs to be flashed or is it a Mac card your are putting from one machine to another? If the latter, then there should be no problems, just make sure all the latest OS updates are installed.
Just be aware that in case you have an ADC equipped card and put it into a non ADC capable board (2x AGP are all non ADC), you will not be able to use the ADC port, due to lack of power.
DVI or VGA works though.
That's because the power in the ADC plug is served to the ADC card by an extra connector in front of the AGP slot. If that isn't present, no power will be fed and a connected ADC display will not power up.
AGP 4x is backward compatible with 2x and 1x to a degree...as long as the voltages are the same. Modern cards run off 1.5 volts while older cards run off 3.3 volts. If you try to stick a 3.3V card in a 4x slot, it won't work, and you'll possibly damage your mobo and/or card.
Also, AGP 8x slots won't accept anything less than 4x cards.
G-News, you're wrong about ADC not working on a 2x slot... the Gigabit Ethernet G4s (400, dual 450, dual 500) all used ADC-enabled cards, yet they only used 2x AGP.
Well, I have personally owned (not anymore, now it's my mom's) a dual 500 system with an AGP Radeon, and I used a 17" Apple ADC CRT monitor on it. Worked great, I like how when you have it connected via ADC, it lets you use the monitor's power button like an actual power button.

It has a DVI and ADC port, and based on this:

even if the ADC doesn't work, the DVI will, which is all I care about.
Thanks again.

the powerbutton thing you mention is a simple consequence of ADC incorporating USB
