Yes! I will try it in the morning. It's now past quitting time and,
following this thread, you will note that the ohci module needed to
be loaded for this AMD unit so the keyboard now works! I will
remove the unused modules tomorrow morning and post hopefully
good news. I used the usbkbd module in a blind attempt to get
things working (I have been following a lot of suggestions).

Cheers,
