no opengl after woody update

[Brad Cramer]

I have a geoforce 256 running the newest nvidia drivers (0.9.6.767) I think.
and I did a apt-get upgrade 3 nights ago and now opengl is broke. No opengl
xscreensaver hacks no quake III no ut. I have checked to make sure I have no
stray libGL* files around and ldconfig -v looks good. Anyone have anyidea
what might have broke my opengl? Also /var/log/XFree86.0.log does not show
any errors.
Thanks for any help.
