It appears that the kdm mem corruption problem is not gone. It still
comes up, but is no longer causing an issue. But did solve the lock-up
as being a swap issue with Kubuntu. Xorg and KDM were simply the
symptom.

Currently using Edgy with xen. Came across a lock up on my monitor. Upon
checking the logs, I found similar messages.
First off, "Can't open default user face" is because the default faces are
missing. Specifically, I did the following:
cd /usr/share/apps/kdm/faces/
ln -s ../pics/users
