Xfree86.0.log error. Please help.

["Greg Hazel" <gah@thalassocracy.org>]

Aside from all the 4.2.1-10 nonsense with the XF86Config-4 changes (ugg,
what a pain) now I'm getting this:

Fatal server error:
Cannot open log file "/var/log/XFree86.0.log"

When reporting blah blah blah

Yes, I've tried 'touch'
/var is not full
the file is only 25k
the permissions are -rw-r--r-- 1 root root
I'm using startx to launch the xserver, which is -rwxr-xr-x 1 root root
/usr/bin/X11/startx I've tried apt-get remove and used dpkg to install
4.2.1-9, with the same results (but it wrote a XF86Config-4 file , yay)

Any help is appreciated,  X is dead until someone gives me the cure :/
