Re: dist-upgrade badly broken-XFree86 -- Fixed

[Ross Boylan <RossBoylan@stanfordalumni.org>]

I was unable to login because /usr/bin/X11/sessreg, which gdm's
default PreSession script invoked, did not exist.  I removed some of
the old X stuff and installed some new things (xutils was the key, I
think) and got the file.

I also had the usual X tweaking to do with the new setup.  Although
it's not documented, XF86 4 has an "IntelliMouse" option to the
"mouse" driver, and that's what worked for me (3 button Logitech PS/2
mouse).  None of the "XXXPS2" settings worked.
