Yes it is resource access control.

If the primary card doesn't work when there's another (unused) card
in the system, then it's probably a RAC bug or a bug with the primary
card driver's RAC settings. Though it's possible that it's just
a motherboard bios bug, like maybe the cards are sharing interrupts
or something. Ideally the NVIDIA card isn't sharing an interrupt
with anything. If this is the case, moving PCI slot the graphics
card is in may help. Though I don't know why this would have
worked with an earlier XFree86 version if this was the case.
Mark.
