Yes. You can use xrandr to set different modes on different monitors.
for example:
xrandr --output LVDS --mode 1024x768
xrandr --output VGA --mode 1680x1050
You also can config in xorg.conf, for example:
Section "Device"
Identifier "Intel Corporation 945G Integrated Graphics
Controller"
Driver "intel"
BusID "PCI:0:2:0"
Option "monitor-VGA" "foo"
Option "monitor-LVDS" "lvds"
Option "DRI" "true"
EndSection
Section "Monitor"
Identifier "foo"
Option "PreferredMode" "1024x768"
Option "RightOf" "lvds"
EndSection
Section "Monitor"
Identifier "lvds"
Option "PreferredMode" "1024x768"
Option "Position" "0 0"
EndSection

Someone else also complain this. See bug #10814.
