xorg.conf virtual screen resolution - help

Hi

I want to ask if anyone can help me set up xorg.conf for using a virtual screen of 1024x768 (at least). I want to use UFRaw but I can't get the window to fit 1024x600. And for some reason, I can't properly Alt+drag the window.

I'm thinking I can use xrandr to set the resolution to 1024x768, and use the screen panning feature - temporarily, just when using some programs. But honestly, I don't know how. When xrandr -- query, 1024x768 is not between the available modes, and I am not sure how to add it to xorg.conf.

Any tips, any help? Thank you in advance!

PS: Using openSUSE 11.0, X.Org X Server 1.4.0.90, RandR version 1.2
xrandr -q returns:
Screen 0: minimum 320 x 200, current 1024 x 600, maximum 1024 x 768
VGA disconnected (normal left inverted right x axis y axis)
LVDS connected 1024x600+0+0 (normal left inverted right x axis y axis) 195mm x 113mm
1024x600 60.0*+ 60.0
800x600 60.3
640x480 59.9
TV disconnected (normal left inverted right x axis y axis)
