Thank you for your detailed posts earlier.  3.5.13 was rushed out and it
does contain some serious bugs.  Many of these bugs have been rectified in
GIT and will be included in R14.0.0, which will be a primarily bugfix
release with very few new features.

Regarding kdm_greet high CPU usage, that bug has nothing to do with the
SAK support, which is why disabling the SAK did not resolve your problem. 
The SAK system has been tested on headless systems, where it automatically
disables itself so that remote logins can still take place.

The kdm_greet bug has been addressed here:
http://bugs.trinitydesktop.org/bugzilla/show_bug.cgi?id=690

The high CPU usage was due to a KDM control pipe polling too often and has
been fixed in GIT.
