Ok, my best guess would be a page-fault-of-doom scenario or a severe GPU hang that is taking down the system. The suggested course of action for both is to try an updated kernel. Can you try to reproduce this on an uptodate stack?

Desktop and simple applications are fine, but opening OpenOffice and FireFox cause the system to completely hang - all I can do is to reboot with the power or reset button. Similarly, the system hangs when any application displays a transparent drop-down menu. When I start a Failsafe session, Appearance Preferences say 'no visual effects' and OpenOffice and FireFox don't hang. So it seems to hang when the system tries to display a 'visual effect' - suspect it is linked to the Alpha Channel functionality. When I load a normal Gnome session, the menu to select Application Preferences displays a transparent dropdown, so the system hangs and I can't check that 'visual effects: none' is not selected... What should happen? The system not hanging would be a good start... I can live without transparent drop down menus for a while. Follow-up: when browsing through the screensavers, one of them ('Euphoria') caused the system to hang. Which rather fits the pattern. Whenever I try to access the screensavers now, Euphoria is the default and the system hangs, preventing me from changing it - which is annoying, but just another example fo the bug at work.
