Valent,
according to what I read, e.g., here

http://www.thinkwiki.org/wiki/Xorg_RandR_1.2#Notes_from_xserver-xorg-video-intel.readme,
the Intel GM cards before 965 only have 11 bit addresses for pixels
and hence can only do 2048 pixels in either direction. Intel simply
made a stupid design decision.

Under Fedora 9 I had a perfectly happy 1680x1050+1600x1200 (3280total) on
two monitors.
Still have the xorg.conf file for it.

Which intel graphich chip do you have and can you please share the xorg.conf?

Thank you.

Valent
The old xorg.conf is attached. Doesn't work under Fedora 10 - kdm.log starts filling up with (while waiting for the login screen to pop up).
[mi] mieqEnequeue: out-of-order valuator event; dropping.
[mi] EQ overflowing. The server is probably stuck in an infinite loop.
