We know Apple deliberately underclocked the chip to 310MHz/278MHz in order to save battery, reduce noise and heat... I'm thinking to bring the speed back to 475MHz/470MHz but kind of afraid the thing's gonna burn, 'cuz it's already running pretty darn hot right now.

Any of you MacBook Pro owners done it?

I used ATI Tools and brought the speed up to 430MHz/400MHz, seems to be alright so far. It gets a bit loud when the fan kicks in but still acceptable nonetheless. Oblivion runs a lot smoother at native resolution now!
