[Ti] Target Disk mode heat issues?

[Kynan Shook]

Yes, that's a fairly common theme while in TDM.  My best guess is that 
open firmware, in order to save space and money in manufacturing, 
doesn't have the code to control processor power saving.  So, instead 
of the computer powering down execution units that aren't needed (or 
even turning off the whole processor for short periods of time), 
everything is running at 100% all the time, generating a lot more heat.
