: 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.
