Today, Apple released an update called iMac Graphics Firmware Update 1.0 which specifically addresses the freezing issue seen on recent iMacs.
This update is for 20-inch and 24-inch aluminum iMac computers with the ATI Radeon HD 2600 PRO graphics processor, running Mac OS X 10.4.10 with iMac Software Update 1.2.1 for Tiger, or Mac OS X 10.5 with iMac Software Update 1.3 for Leopard.
According to Apple, the download updates the graphics firmware on the ATI Radeon HD 2600 PRO card to address issues that may have caused the computer to freeze.
Early reports from iMac users have been promising. One user posts that his benchmarks before and after update are the same, so there's been no speed downgrade involved in the fix.
