I'm here to say me too but I'm on a Dell Inspiron mini 10v running the 64 bit version of Kubuntu. Seems to happen reliably when trying to send video to aMSN and sometimes with the Citrix client 11.1. Also seems to happen after hibernating a few times. Sometimes restarting kdm works, sometimes not. Really not sure if it helps but attaching xorg.log
