Issue with PM G5 1.8 GHz SP : temporary solution...

While we are desperately waiting for a firmware update for the PMG5 1.8GHz SP Rev 2, Apple is proposing a temporary solution :
1) in preference panel, unselect sleep mode for the computer and the screen.
2) Select highest performance mode.
In summary... nothing new. But at least this TechNote confirms that Apple is aware of the problem and acknowledges it while trying to setup a fix.
