I've seen some reports related to problems with the VGA output in X40 
ThinkPad notebooks:

xserver-xorg-video-intel: corruption on external VGA display
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=569135

[i855gm] VGA out flickering after upgrade to lucid (regression)
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/589140

After reading the bugs, it is still no clear (at least for me) if the 
problem can be bypassed somehow (by installing an updated video driver/
xorg version/kernel) or still open/unsolved.

Sorry to be so fuzzy, maybe someone here can provide updated/accurate 
data on the matter :-?
