Hi Daniel,
your problem is that the system BIOS is buggy and doesn't assign
resources to the card:
> Region 0: Memory at <ignored> (64-bit, prefetchable)
> Region 2: Memory at <ignored> (64-bit, prefetchable)
> Region 4: I/O ports at 9000 [size=256]
> Region 5: Memory at <ignored> (32-bit, non-prefetchable)
> Expansion ROM at <ignored> [disabled]
The kernel actually tries to assign resources to the bridges, but fails
as well because the BIOS didn't reserved any during startup.

There isn't much you can do except for trying to update the BIOS and if
that doesn't help replace your motherboard.

Christian.
