GDM won't load, commenting both of them makes GDM happy.
If I kill GDM & X, and then start the desktop with "startx", everything is fine, with "v4l" and "XaaNoPixmapCache" enabled or not, so it must be something in GDM that is triggering a failure in X.
In brief, the problem is: "intel" driver + "XaaNoPixmapCache" + "v4l"
Using Intel driver I found that if xorg.conf has the following lines:
Section "Device"
Option "XaaNoPixmapCache"
EndSection
...
Section "Module"
Load "v4l"
EndSection
