Re: Quicksilver issue
Try unplugging all the USB stuff. I eventually figured out that my wireless keyboard was causing my Mac to randomly wake up from sleep. It also happened with a Logitech wireless mouse but the latest Logitech software update seems to have solved that for me.

When it comes to USB stuff some computers act just strangely. I had a laptop that rebooted reproducibly if I touchted the USB port with an external USB device – must have shorted some circuit or something. No damage done, just lost all unsaved files :-( But if you find something: I'm interested too! I know that was no help at all… Sorry.
