I have a Viao laptop with a Mobility Radeon  video card running Debian unstable.

I have to apologize for not remembering the procedure for setting it
up, but all the files came off the Debian tree. There is an ATI
Control panel (read GUI) which lets you control the internal and
external monitors.

I ran the both monitors for a while, but the larger external monitor
won out.  Here's a clip of the relevant sections of the xorg.conf
file. I found this somewhere on the internet and just fooled with it
until it worked. I have the fglrx-control, -driver, and -kernel-src
version 8.28.8-4 installed.

Hope this helps.
