I am using two variants of 3c589 card with a cardbus bridge with only
minor glitches related to suspend/resume.
I think it worked with the default kernel, I only used the io
specification for an isa bridge that is broken now. I am not sure what
exactly this does but I was reading some page that said something about
16-bit /24-bit io spaces which should not apply to a cardbus/pci bridge.

I get:

Bridge (rev 0x01)
cbb1 .. .. function1 ..
