@Alberto:
Here's a patch that adds calls into pm_vt_switch_{required,unregister}()
to the NVIDIA driver. It resolves the corruption issue on my test
system. This change will be included with the next release of the 331
series drivers.
** Patch added: "NVIDIA driver patch for pm_vt_switch_required()"
