Further update for anyone who's curious.
Thank you for contacting AMD Global Customer Care.
At this point there are no plans to release updated versions of the Dual Core optimizer and the AMD Cool'n'Quiet drivers (which are listed as Processor Drivers on our website). We are not currently aware of any compatibility issues of running SP3 and installing the AMD Cool'n'Quiet drivers; some users have reported that in some instances, the "ATi Smart" utility (ati2sgag.exe) may cause Cool'n'Quiet not throttle the processor down properly.
The AMD Dual Core Optimizer has nothing to do with processor power state changes; this optimizer is designed for systems which experience instability with applications when used with a dual core processor. This optimizer is merely a registry modification which causes Windows to use a different processor timer to compensate and bring performance back to normal state. As with the C'n'Q drivers, there are no known issues installing the optimizer with SP3.
If you are experiencing error screens or un-explainable behavior, please include screenshots so we can assist you if possible.

It sounds like the Dual Core Optimizer is redundant now that SP3 includes the Microsoft fix, so the Processor Driver is the only thing that needs to be in. Has anyone noticed any issues when following these steps?
