[DJR013 <djr013@xxxxxxxxx>]

I just ran xorg-edgers' ppa-purge and tried the card again. I have
enabled compositing in Metacity. One test was selecting the Applications
menu and rapidly switching through that and Places and System, which
eventually froze X. After doing Alt-SysRq-K, it allowed me to log back
in, and I tried again with no problem; I opened some semi-transparent
terminals, enlarged them, and moved them around over eachother. Trying
to enlarge the ~eighth terminal froze X. Eventually I had a kernel
panic. Occasionally I can't even boot fully. Sometimes X will freeze and
allow cursor movement, other times won't. Has occured a couple times in
a (Ctrl-Alt-F1...) virtual terminal.

Often I see colorful flashing as textures load, particularly at boot.
Once I rebooted and seen the screen as it was when X froze, for a few
seconds, and it cleared and finished loading GNOME.

I suppose there is a chance the card is defective...but it has no
problem with the NVIDIA binary drivers. (As an aside, I even had Compiz
running in Nouveau for some durations before freezing.)

I may try booting an Live session soon to see if it happens there too.
