Enabling "TerminateServer" in the kdmrc file seems
to work around this.  I still get a /Xorg.core
file but kdm seems to recover and allow me to login
again.

BUT, now Ctrl-Alt-F# shows a messed-up console
(Ctrl-Alt-F9 gets back into KDE just fine).
Clearly, the video card is still getting wonked.

I'll see if I can build an Xorg server with debug
symbols and get a backtrace.
