x.org nvidia driver problem

[Samuel Thurston, III]

I just upgraded to Hoary.  x.org is no worky.  

/var/log/X.org.0.log says that my kernel module is version 1.0.6111
and that my x.org driver module is for version 1.0.6629.

I'm kind of at a loss here since as far as i can tell the kernel is
fully up to date and I have the newest version of the nvidia drivers
installed according to apt.

if i can't get this working within 48 hours or so, i'm going to have
to roll back to warty.  is this possible short of an all-out
reinstall?
