Thanks for the tip. I'm just now getting back to this issue 
after installing 6.2 Stable AMD64 on a newly acquired hard 
drive. And I have the above drm lines in my kernel, but the 
display still goes blank when I startx.

Some small headway: The problem with the display (which is now 
a SyncMaster 940t connected to the Radeon 9600 Pro DVI out) 
being driven out of range (I assume) and going blank was 
solved by setting the option NoAccel in the device section of 
my xorg.conf file. I've also tired both the  "ati" 
and "radeon" drivers, and both give identical results.

With acceleration disabled image tearing is bad, jumpy really,  
that is when one is dragging an X-term around on the desktop 
(xfce4.) But at least I've got a workable display now.

I've been trying several and varied radeon driver "option" 
settings / combinations to see if I can get a viewable 
display with acceleration, but no luck yet.  Maybe someone 
using the Radeon 9600 Pro [RV350 AP] video card with a 
similar TFT flatpanel will chime in with their experiences 
and / or workable settings.
