Maybe the pci support code is checking a wrong bit?

I have seen this before.

I have a MB which has a jumper to enable/disable PS/2 mouse I/F. I had
this jumper set to the "enabled" position and naturally could use the
PS/2 mouse. But, the verbose listing showed "Mouse IRQ12: disabled"
like yours.

I also heard from someone who owns a MB whose PS/2 mouse I/F can be
controlled via the BIOS setup menu. His verbose listing also shows
"Mouse IRQ12: disabled" despite that he has enabled the PS/2 mouse
I/F.

At that time I didn't pursue the matter any further because it didn't
seem to have ill effects.
