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.
