There were no freezes after I disabled the screensaver on the Vostro V13. Also, while the screensaver was enabled and X froze, after killing X through a virtual console and restarting it, it could be seen in the gnome system monitor that Hufo's Tunnel was using ~ 100% CPU; moreover, Helios was also present on the task list, even though I had selected Hufo's Tunnel as the screensaver (then again, it might have to do with the fact that I have not rebooted that machine since).
