That's scary indeed! my Macbook Pro(15" 2.4Ghz, Late 08) also got up to above 85c under bootcamp windows xp, and the fan seems staying at 2000rpm.
One funny thing that I found is that, my MBP will goes extremely hot in windows xp, I'd installed speedfan just for monitoring the temperature, and found that my MBP went up to 80c, just right after 10-15mins got into the window. Just got safari and itune opened.
However, I continue to start up GTA4, then I heard the MBP's fans start to increase the speed(noise). and after a good 30mins of messing around in GTA4, I quickly switch back to desktop and check that, the temperature draw back to around 75c, how strange... I guess it could be the MBP fans start doing their job. Then I close the game, the fan's noise decrease / slow down. And next after a while, the temperature gone back up to 81c - 82c .
It only got up that high temperature under windows XP (haven't try Vista or Windows7). In OSX it's nice and cold, so far the highest temperature is about 55c under OSX.
I did some searching on web and see that "Electrical and operating requirements" on Apple's support page.

# Operating temperature: 50° to 95° F
(10° to 35° C)
# Storage temperature: -13° to 113° F
(-24° to 45° C)
Operating temperature is between 10c - 35c? So keep running it at 80c is like killing my MBP?
So, I call up Apple support, and they told me that they aware of this problem happening under bootcamp windows, said, it's best to keep the MBP under 60c .... and, better don't play any intense game on the machine.
Then, I asked if there any solution, he replied me have to wait on a new firmware to fix this, but he couldn't provide me more details on it further....
