All right.
I was asking because I have seen two xorg.conf's from gutsy (my T23 and 
a Panasonic Toughbook) so far, both without sections "Modules", 
"Extensions" and "DRI". So this is something that has changed in the 

Maybe you could get back on the road by getting a basic xorg.conf 
generated automatically (taking care of inputs and graphics card) and 
then manually editing to fit your screen in:

Automatic xserver configuration is done by:
"sudo aptitude -phigh xserver-xorg"
(I hope I got it right this time :)

Then overwrite the section "Monitor" (only this one) in the new 
xorg.conf with the same section from  the old xorg.conf. Or just edit 
the figure in the new xorg.conf to what they are in the old xorg.conf.
