I have made usb bus_dma aware.  I have only tested this patch so far on
an ohci controller in sparc64.  I do have problems with isochronous
transfers, but I don't have an i386 box to test the original code on to
make sure it isn't my changes.  Currently both umass and ums have been
tested and are working on sparc64.  I would like to receive feed back
on i386 to make sure things don't break there.

The patch is at:
