: 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.
That would be 'no, it doesn't go through a bridge'. I'm not sure
either, but it has been observed before.
