No, there's really nothing special involved, unless you consider the fact that the PCI card is in a PCI-X slot on a dedicated bus. Perhaps you have a bandwidth issue on your hands.
This is definitely not the case, because I don't have this problem with the open source nv driver: it therefore has to be a software issue, but it's possible it could be a problem with the nvidia driver not dealing properly with a BIOS setting, or having some wacky XF86Config option I haven't set. Andy said last week he would look into it, but I haven't heard back yet.
