I've found and read the spec. I think it has all the info to come to a
fully working version eventually.

This is ok. (D0)
I did some checking with pciconf before and after suspend and come up with
the following "fix":
# set nambar
pciconf -w -b pci0:31:5 0x11 0xd8
# set nabmbar:
pciconf -w -b pci0:31:5 0x14 0x81
pciconf -w -b pci0:31:5 0x15 0xdc
# set pcicmd:
pciconf -w -b pci0:31:5 0x4 0x5
I hacked the same thing into ich.c, that works too, but is not very clean.
Anyway that still doesn't seem to really solve the problem as that won't
help the hang on module reload. I'll investigate further.
