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....
