Hi David,

A couple of thoughts (after reading Clives response).  Look at the
successful FC4 xorg.conf file and use it to make a similar video
configuration (see if you can select the horizontal and vertical retrace and
other parameters during the install process to be the same as those chosen
by FC4).  Breezy was a bit unstable on our Inspiron 8100 until I did just
that.

In your CMOS setup, see if you can lock the laptop into a slower clock rate
(CPU clock rate).  It might some sort of clock rate control problem.

Try live Knoppix and check out the setup (video, power management, etc.)
see where the two differ.

Good Hunting!

Tod
