PAM anyone?

Hello collective intelligence... 

My /home partition got full and the machine got unstable.
I deleted some big/useless files, fsck(ed) the oartition with no errors and 
rebooted the thing to be safe. 

Now I can't login to KDE and I get this error in /var/log/auth.log:
pam_ck_connector(kdm:session): nox11 mode, ignoring PAM_TTY :0
Anyone has a clue?
Tnx.
