  pci=3Dbiosirq=20

and maybe even more important

  pci=3Dassign-busses

as a kernel boot-parameter. cf.

as i suppose that your wifi card is a carbus-type-card, the the first porti=
on=20
of your device number (02:00.0) should differ from the device number' first=

portion of your cardbus-controller. to me it seems that your controller and=
=20
your card do something like share the same id...

in my case the cardbus-controller (something from RICOH, as i recall -=20
notebook is off right now) has the device id 02:00.0 and the card gets=20
03:00.0 or 05:00.0 depending on the cardbus slot i stuck it in.

if this is not the case an irq will not be assigned properly for your card.=
=20
try pci=3Dassig-busses. the whole issue is solved in kernel-2.6.x.

i had this problem (which was a general cardbus problem) on an asus l3c=20
notebook...
