Victory!

I now have virtual scrolling/panning on my 1024x600 screen to 1280x1024
whether or not an external display is connected to the VGA port.

thanks Sam - you inspired me to keep trying.

Turned out that it finally did work but what made it work was adding
back the second Monitor and Screen sections so I could have both my LVDS
and VGA screens and I gather that the larger size of the VGA is what
made it all work.

I have put this info on the Acer Aspire One page on Fedora Wiki for
anyone who is interested and it should provide a really good guide for
Sam's Asus eepro (obviously adjust for the built-in video and external
VGA display).

Oh - this is with Fedora-11-Beta (and current updates) because I believe
the xserver 1.6 and xrandr 1.3 versions are needed to make it work.
