Public bug reported:

Binary package hint: xserver-xorg-video-nouveau

I'm not using the nouveau PPA.  Recently nouveau arrived in the lucid repository, and was working fine for me (well done!).
But after a recent update, when gdm starts I get the nv driver, not nouveau.  In Xorg.0.log I see:
[drm] failed to load kernel module "nouveau"
I discovered the following work around: (1) stop gdm  (2) modprobe lbm_nouveau  (3) start gdm
Doing "modprobe lbm_nouveau" causes the screen to go black, so I actually do "sleep 1m; start gdm"
in another console before doing the modprobe.  The result is that gdm starts up with the nouveau
driver, and all is well.

Here is the initial part of a diff of Xorg.0.log, between the one that failed to load nouveau, and the
other that did load nouveau:
