Hm,

I had a similar problem on my Toshiba 9000 to get the build-in
MiniPCI-WLAN working. The 9000 is built around the Intel 830M
Chipset. The interrupt router on this "thing" is an 0x248c8086 (0x248C 
82801CAM LPC Interface) and has 8 intr lines, but only the first 4 are
used due to pcibios assuming there's some "standard" chip (0x122e8086
which translates to 82371FB PCI-to-ISA Bridge (PIIX)).

To get wi0 up and running I've done a really ugly hack in pcibios.c,
resetting 0x122e8086 to 0x248c8086 (#ifdef'ed TOSHI9000 of course ;-)
and added 0x248c8086 to the list of known chips in pci_intr_fixup.c
with logic to set up the additional 4 interrupts.

If anyone is interrested to get the hacks, I'll mail the modified
files...
