The multiple detection _was_ just a minor inconvenience. However, fixing it
just happened to avoid an oops elsewhere, which always happens after an HP8100
is detected 8 times.

I'm going to be away for a while, but if someone could fix the original
problem, then we wouldn't need this workaround. An alternative workaround
would be to add the HP8100 to the blacklist, but fixing the real problem
would be preferable.

Unfortunately, the only properly decoded oops I've seen isn't very helpful...

Michel - could you repeat the problem, and try to catch the _first_ oops of
the pair. Then decode it as you did the other one, and post it to the mailing
list. Someone should then be able to take a closer look, and if they don't
then I'll have a look when I get back in a fortnight.

Try using a bigger video mode, if the first one was scrolling off-screen.
