Error 0911 is some sort of a keyboard microprocessor synchnronization problem
and is definitely heat related.  Apple DTS told me that 0911 is often heat
related when I started getting lots of the errors this past summer.  The
problem disappeared when cooler weather came in the fall until a few weeks
ago when I installed a TransWarp GS in my machine.  This added enought
additional heat that I started getting 0911s again.

When I have the 0911 problem, I pop the cover on my GS and run with the
cover off which cools the machine down and solves the problem.

As a (hopefully) permanent solution to the problem, I've got a Kensington
System Saver GS on order.
