Confirming the same bug on my HP zd7000 laptop with nvidia-restricted- glx & powernowd. In my case X.org was was pegging the CPU after no keyboard use for ~30 minutes, eventually locking the machine. The same thing would happen if I locked the workstation. Definitely seems to be related to ACPI as the workaround specified above /did/ eliminate the lockup.
