I don't know, but it looks like cbb0 is directly under pci0. Here's the
devinfo -r results from his working boot:
pcib0
pci0
pcib1
pci1
cbb0
Interrupt request lines:
0xb
I/O memory addresses:
0x50000000-0x50000fff
cardbus0
pccard0
cbb1
I/O memory addresses:
0x50100000-0x50100fff
cardbus1
pccard1
I can't see how ACPI sysresources affect this since ACPI doesn't claim
0x1080-0x10ff IO which the card asks for.
