As to those who continue to doubt the stupidity of Intel's mobo

Desktop Board D915GVWB" machine with a TDM04B board:
And the saga continues...
'lspci -vb' does not understand IO-APIC mode, as best I can tell, so the
interrupt number that it reports is totally useless.
On my desktop machine, with an nVidia graphics card in a PCI-Express
slot, /proc/interrupts shows it using interrupt 185, and 'lspci -vb'
shows it using IRQ 10. It is most definitely _not_ on IRQ 10, since
/proc/interrupts show the actual mapping from the IRQ controller (the
APIC) to the driver servicing the device.
At best, 'lspci -vb' is showing what interrupt the device was on
_before_ the kernel reassigned it using APIC mode.
