[ltp] Multi-headed desktop with ATI Radeon Mobility 7500

[Krishna Sethuraman]

[Now with file attached!]

*WARNING*: If the LCD screen flashes white and goes fadey (I can't find 
a way to describe this properly) and is allowed to sit for some time, 
I've been told it can damage the LCD screen.  If you see this, try 
anything to blank the screen; switch to a different virtual console, 
fn-f3, or force power off. *WARNING*

...
display properly.  My configuration is attached at the bottom, in case 
someone wants a simpler (or just a different) multi-headed XF86Config 
to tinker with -- and heed the *WARNING* at the beginning.

The major point I noted was the 'NoDDC' in the Device sections, and of 
course your modelines will differ, definitely for your external 
monitor.  FYI, this file was autogenerated by kxconfig for XFree86 
v4.2.something, and modified by hand to add the Xinerama functionality.
