well, the following is completely untested. Lemme know if it works. It is too green to go into the tree as-is, but will (if it works) get you up and running. It won't work for anything but a real pci cardbus bridge (or the wannabe cardbus bridge the ti-1031). Some ISA based chips can also do it, but I don't plan on supporting those because there are too many different ways to do it, it won't work on real ISA cards, just funky wired chips in laptops, and there's little demand. this patch should also apply to -stable cleanly.
