Well, driven by need and desperation, what else can I do?  We just got
16 dual PII's, all with 7860's (so far so good) and 7890's (uhhh, BAD)
onboard.  SO, it is time for me to tackle the U2W problem anyway, and
if you have a start for me, so much the better.

Send me a URL, together (if you don't mind) with a short note on what
you've already done and I'll have at it.
