Kynan - your advice to David on his 'sleep' problem was very helpful,  
I am sure.

Once thing you mentioned was reloading the firmware.  I do not  
believe that I have ever done this, nor do I know what kind of a  
problem it would solve.

Is there any guideline you have on this?    I would assume that it  
applies to 'fundamental', low-level problems.

Is it something that can be done with no negative consequences?

Is this key combination applicable to all Macs running OS X?
