I previously installed Mint 14, and attempted to install native drivers and issue here: viewtopic.php?f=59&t=120216&p=661781#p661781
The fix I was referred to was in: viewtopic.php?f=59&t=119819
I followed same instructions so that machine will run cooler, but the fix seem to completely hose up system and xserver would not start.
I had to reinstall back to clean Mint 15 install to get graphics to work and it is now running very hot.

I don't know if there is a way to get native drivers working and machine cooler, or if I need to fallback to Mint 14.
