After installing the proprietary Nvidia driver, it would also wake up from suspend. A nice touch

There's also a windows box on the LAN, so I used samba to be able to connect to its shared directories.
Now, when I choose "suspend" from the menu, the screen show funny patterns and goes blank for a few seconds (as expected),
but instead of switching off the screen it asks for the current user's password (which I explicitly disabled for suspend using gconf-editor /gnome-powermanagement).
If I first unmount the samba share, suspend will proceed without problems.
Any hints on how to make it either:
* suspend properly despite having a samba share monuted, or
* auto-unmount the share before suspending (preferably with some "force" option since it frequently looses the connection resulting in long delays for any network operation)
