dmesg and look for other PCI devices on the same bus as the cbb
device. You'll see something like:
pcm0: <ESS Technology Maestro3> port 0xec00-0xecff mem 0xf8ffe000-0xf8ffffff irq 5 at device 3.0 on pci2
cbb0: <TI4451 PCI-CardBus Bridge> at device 15.0 on pci2
fwohci0: <Texas Instruments PCI4451> mem 0xf8ff8000-0xf8ffbfff,0xf8ffd800-0xf8ffdfff irq 10 at device 15.2 on pci2
etc.
Next, look at the addresses used by the various devices on the bus.
This means that something like 0xf8ff0000-0xf8ff7fff is free on the
bus. This would make a good range to allocate from maybe. If you see
a lot of ranges 256 bytes in size, you might have some issues with
prefetchable vs non-prefetchable issues. But I'll ignore those for
the moment.
