Hi, all!
I has bought UHCI on Cardbus card.
SUGOI CARD X3UFL: http://www.system-talks.co.jp/product/sgc-x3ufl.htm
However not found the uhci at cardbus driver. I copied and edited
by ohci_cardbus.c to uhci_cardbus.c, and referred to {ohci,uhci}_pci.c.
I was successful to attach uhci at cardbus on evbppc (OPENBLOCKS266).

But userland was hungup every moment. X-<
I can't test on i386 machine. Please test if be interesting you. ;-)
