I've found that Linux up to  2.6.9 (I haven't tested .10)  Dosen't do
this fully.  With my 440bx chipset there are config registers in the
northbridge that control which IRQ line each of the PCI PIRQ lines are
routed to.  Even with a proper PIRQ table these registers are not
setup and I get the same error reported.

I have code in my final_mainboard_fixup() that sets these registers
such that they match my table and then every thing works fine.

I suggest you diff the output of lspci -xxx for the northbridge
between linubios and factory bios and resolve all the differences with
the datasheet.
