Here's the thing though...
Apple has no mention of SLI capabilities...
Yet they space the 16x & 8x slots apart, as if to allow space for two Quadros...
And the SLI v1 spec is for dual 8x slots, right...?!?
And we all know how Apple likes to cripple capabilities in early revisions, only to enable them as new features in later revisions...
Mmmm... Dual Quadros in SLI mode running quad 30" ACDs... That's what? 5120x3200? I just know those bastards down in the R&D labs at Cupertino have a patch to enable such a beastie... Probably had a custom bezel made for it, and got those LCDs as close as possible...
Or (if running quad GeForce 6600s) one could go either 6720x2100 (with octo 20" ACDs) or 7680x2400 (with octo 23" ACDs)...
I like the idea of the quad 30" ACDs running as one unified display, but in a sort of SLI mode...
You know, big and fast...!
That's what I would do, if my new numbers hit the Lotto...

whoa. one valium over here, thanks.
but you are right
you could have 16x sli via 2 slots running 8x.
so 1 quadro goes into the 16x slot. "The NVIDIA GeForce FX 4500 graphics card occupies the 16-lane PCI Express slot and adjacent PCI Express slot." as apple says.. so this means you could pop another quadro in the 8x slot and that will take up the space of the 4x slot as well. now, the SLI bridge connector, apple-nvidia quadro sli driver from the secret driver lab, and one is all set to go
somewhere in cupertino there is the "secret driver lab" where they are coding this stuff to be used in powermacs. like the underground bunker thingy in Lost http://www.nvidia.com/object/quadro_sli_faq.html
What is SLI for NVIDIA Quadro?
* SLI Frame Rendering: Combines two PCI Express graphics cards with an SLI connector to transparently scale application performance on a single display by presenting them as a single graphics card to the operating system.
o Benefits Visual simulation, broadcast, and video applications that are fill ratelimited will benefit from using the split frame rendering (SFR) mode.
o SPECviewperf 8 and other applications that are geometrylimited will benefit from using the alternate frame rendering (AFR) mode.
o Two identical NVIDIA Quadro graphics cards (4500, 4400, 3450, 3400, and 1400)
o SLI connector
* SLI Multi View: Combines the power of two NVIDIA Quadro PCI Express graphics cards to span a single hardware-accelerated OpenGL application window across multiple displays, run a single application per GPU with multiple display outputs, or enable other flexible usage of two PCI Express graphics cards.
o View professional applications over multiple displays to increase visual real estate.
o Run a single application per GPU to offload geometry processing to a second GPU.
o Any two NVIDIA Quadro PCI Express graphics cards: NVIDIA Quadro FX 4500, 4400, 3450, 3400, 1400, or 540
