I bought an OHCI cardbus card a few months ago for work, and almost got it
working.  The issue is the linux1394 driver initialization subsystem,
which is incompatible with both CardBus and the newer 2.4.x PCI subsystem.
I rewrote it to deal with all forms of probing (2.2.x, 2.4.x, and old
pcmcia_cs), but can't quite get the OHCI card to function.  It's losing
most interrupts.

I should have time and priority to hack on the work in a couple days, so
I'll apply the changes to the latest code and put out patches.  I would
expect that once validated they'll make their way into the main CVS repo,
since they're necessary to be fully correct in 2.4.x kernels.

Stay tuned....
