Yes! I can login as a new user. Switched xorg.conf back to using xfs, 
and that worked to.

( Oddly, when I logout as the new user, I'm left at console 7 with a 
black screen and a blinking cursor at top left. console 1, witch I have 
to manually switch to, shows the usual X shutdown stuff.)

Well, it appears to be font related. I hope you can figure out what the 
font problems is though. Here's the backtrace:
