iMac and pmud

[Jakob Malm]

Are there any risks with running pmud on an iMac 400 DV? Almost 
everywhere I look it is only mentioned in connection to Apple portables.

I have been using it for a little while now, and sometimes (not very 
frequently) after having issued the snooze command it goes to sleep, but 
makes funny noises. Sometimes it just shuts off the hard disk and not 
the screen (it goes black, but is still on). Can I do something about it?
