Not that I'm aware of.
$ ps aux | grep kdm
gg        6795  0.0  0.0   4008   524 pts/2    D+   18:35   0:00 grep
--color=auto kdm

the odd part is that the process PID changes each time:
$ ps auw | grep kdm
gg        6878  0.0  0.0   4008   752 pts/2    S+   18:43   0:00 grep
--color=auto kdm

I seem to recall that there was a thread sometime back that indicated
that this process isn't the actual 'kdm' but is an x process of sorts.
I'll see if I can find it.
