It's an odd issue alright. And I empathise that your frustration level will be quite high by now.
Just to clarify, It was definitely XP 64 and not XP 32 that it was working on before and it was the exact same setup?
Was it an in-place upgrade or a fresh OS installation?
Are the monitors DVI or VGA connection? I had a black screen issue on 7 with a particular nvidia driver and connection (probably unrelated, just an idea)
When you installed Vista, did you install with both cards+bridge attached+8GB?
What happens when you you use only one monitor connected?
I know you mentioned you tried driver sweeper when removing/re-installing drivers. Did you also remove the physx component as well?
Was your method:
Uninstalling the drivers + physx through the control panel, running driver sweeper as admin in safemode to clean both nvidia and physx componenets.
Removing the 2nd card. Re-booting and then re-installing the drivers with one card only, single monitor +8GB and then adding the 2nd card and bridge?
If not, that's one method I'd try.
Sorry to make you repeat yourself, but I know for a fact that it should work. I've crosfired (similar enough to SLI) both 512/1GB card models + 8GB and not had this issue.
