Sorry for the confusion, but both usb-uhci.c and uhci.c will be deleted anyway :)
I am more interested in usb-uhci-hcd.c and uhci-hcd.c drivers, which both showed up in 2.5.16. Yes they are based on the previous usb-uhci.c and uhci.c drivers respectivly, but they are a bit different (they use the hcd core code which reduces the size of the driver.)
You also might want to check out uhci.c again in 2.4.19-pre. It has had a lot of previous bugs fixed and works _much_ better for me than before.
