problem exiting X

I'm posting this here on the off chance someone else has encountered it.  I 
can't find the appropriate forum on X.org, the suse-laptop list is German 
only, and my post to suse-linux-e hasn't given me an answer.

Installation of SuSE 10.0 on my new HP Pavilian xv6000 went incredibly well, 
the easiest laptop install I've ever done.  I'm left with one problem, 
hopefully not a show stopper.  Card is ATI Radeon XPRESS 2000m 5955

The widescreen 1280x800 works great while the window managers are running, but 
X won't exit properly.  Regardless of whether I exit to gdm or console, the 
screen turns into a gray color, sometimes tinted with various colors, plus 
some horizontal and vertical lines.  At this point the screen will not 
recover.  Pressing <alt>F2 -F9 while X is running causes the screen to do the 
same thing.  The problem occurs with KDE, GNOME, and FVWM2.   It's not a total 
lock, as the three finger salute properly reboots the computer after an 
orderly shutdown.

Skipping all window managers, i.e., simply typing "/usr/bin/X11/X" at the 
command line in runlevel 3, then pulling the rug out 
wiith  <crtl><alt><backspace>  gives a normal exit to a good console.

Is there something I can put in .xinit or somewhere that will fix this?
