Good point, but AFAIKS, the permissions on the file remained 644
from July 2010 right up until it was modified on February 18.  
Whatever it was, it did it twice, because it also overwrote
xorg.conf.backup (!).  Fortunately, I have nightly backups for
years, and I also make copies of my xorg.conf file, ( i.e.,
/etc/X11/xorg.conf.20100705 ) every time I mod the file.  The
main annoyance was figuring out what was going on.  The subsequent
slow behavior was mostly evident in Firefox, so I spent way too
much time trying to diagnose that. 

I don't like mysteries - if the nightly updates did not do this,
then something nasty is occuring.
