Update: This machine has been usable since this happened
in Win32 (dual boot) as long as I don't do graphics work
or play DVDs or games or anything.

Today, I booted back into FreeBSD to sync some files with
my Gentoo machine (which I have been using as my primary
desktop since this happened to my FreeBSD laptop) and on
a whim I pushed VERY firmly on the space of plastic between
the power button and my display.

Miraculously, the screen garble ceased! About 5 minutes
later it came back, so I repeated the proceedure and it's
fine again.

Gee, if my video chip was toast, I don't think pushing on
the plastic would help. It looks like I've got a loose connector
somewhere. Anyone have any ideas on what to check? I already
tried reseating the LCD connector... and the garbled output
appears on external CRTs too...
