I found out the same thing... my firmware is installed, but it didn't 
fix it either.

Exactly! My MBP is on AC all the time, and I get that too - especialy 
when I'm backing up (not a great time for a shutdown!).

Have you tried this? The reason I ask is that my understanding is that 
it's a logic board issue, not a battery issue. If that's really working 
for you, I'll try it myself and let you know if it works for me. But in 
the meantime the smcFanContol software was really saved my butt...
