Following Wil's suggestion I've ssh'ed to the computer. When the lockup occurs, Xorg spikes to 100%... well I think it's 100%... even the ssh connection freezes for the duration... but when it happens, top via ssh seems to trap at least part of the Xorg going nuts and I see it bump to the top of the list, and show 95% CPU or higher... that's 95% across 2 cores.. normally when one core maxes, top shows 50% CPU. This appears to be pegging both cores to 100% for a short period.
Xorg version is 7.5-11.3-x86_64 from openSUSE OSS repo.
So.... an Xorg problem? Could it be related to installing the nVidia drivers? Disabling KVM? Using nomodeset?
OK, more work on this... and I might maybe have at least found a way to stop the freezing from happening.
I've installed kernel 2.6.35-rc6 from the Kernel Head repository, and a side effect seems to be that... the freezing has gone away.... so far. Watching top from another computer ssh'ed to the server, and Xorg is behaving itself... bouncing between 2% and 25% (peak) remaining usually around the 10% mark while events are happening on the desktop.
So.... not sure how to ID the root cause... but it seems to be sorted in a newer kernel.

I hope you open a bugzilla so Stefan Dirsch can be made aware. He handles the graphics drivers. You can assign the bug directly to him "sndirsch at suse.de" and it will skip the front door team which can take a few days (or more).
