iMac Freezes Fixed with iMac Graphics Firmware Update 1.0
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.
Numerous reports confirm that it does fix the problem that has been widely reported. One report is reproduced here:
Guys, this update is the real deal. I have a bad freezer that is actually scheduled to be shipped back to Apple for a replacement tomorrow. I applied the firmware update (and 10.5.1) and have been working it hard for the past two hours, doing all the stuff that used to make it freeze in minutes. iTunes visualizer, CoverFlow, screen savers, Photo Booth, Front Row, the whole nine yards. Not a single freeze. I had this thing freezing on command before.

Not every 20-inch and 24-inch aluminum iMac computer requires this update. If you are not automatically presented with this update, your computer does not need it.
If you manually download this update and attempt to install it on an ineligible computer, you will receive an error message.
If you manually download the update and receive the following error message when selecting a volume, "You cannot install iMac Graphics Firmware Update on this volume. Your computer does not need this update," one of two conditions exist:
* You have not installed the iMac Software Update 1.2.1 for Tiger or iMac Software Update 1.3 for Leopard. From the Apple menu, select Software Update and install the appropriate software update, and then reinstall iMac Graphics Firmware Update 1.0.
* You have already installed this update.

So far so good, but it's only been about 5 minutes so we'll see.
so did they just clock down the card to fix the heat issues?
Hold on, lemme drive home, install the update, call the engineer i know at apple and ask him.
At this point I dont believe anyone would really know. Pure speculation seeing as how the card is already clocked down as it is.

Lets not get hostile now. We all just have hopes that this issue is gone for good. Some of us wonder how it was accomplished that's all. Also with the speed of the internet these days, I would not be surprised that someone not within Apple already knows this info.
