I too have the RmInitAdapter problem. I didnt notice any disabled interrupts though. In fact, the first (EE) line in the X log is this:
(EE) NVIDIA(0): Failed to initialize the NVIDIA graphics device PCI:1:0:0.
I have an Intel DG965RY mainboard, Core 2 Duo CPU, 1 GB DDR2 SDRAM, Serial ATA HD, Serial ATA DVD Drive.
A bug report and the Xorg.0.log are attached.
