Apple Releases MacBook Pro Firmware Update to Fix Unexpected Shutdown Issue
Apple has released MacBook Pro SMC Firmware Update 1.5. The update fixes an issue where the machine would shut off unexpectedly under heavy processor load, even when plugged in.
This update resolves an issue where a MacBook Pro being used with a power adapter may unexpectedly shut down under heavy workload if the battery charge level is near empty.
Your computer's power cord must be connected and plugged into a working power source, or your battery must be at least 25% charged.
When your computer restarts a gray screen will appear with a status bar to indicate the progress of the update.
Your computer's fans will run at full speed during the update but will return to normal speed once the update completes.
Do not disturb or shut off the power on your computer during this update.
MacBook Pro SMC Firmware Update 1.5 can be downloaded from Apple's support website.
The update applies to owners of MacBook Pro models 8,1, 8,2, and 8,3. These include both MacBook Pro (Early 2011) and MacBook Pro (Late 2011).

So, that's all 2011 MacBook Pro models (all sizes)
Before installation, the warning:
Before installation my SMC version was 1.69f1
Now the SMC version is 1.69f3
Early 2011, 15" MacBook Pro (MacBookPro8,2)
I only posted a portion of the script - the portion that specified what models were supported. You need to make sure you're running at least 10.6.8 or 10.7.2 in order to install the update. You'll get those messages if you aren't up to date with at least one of those OSs.
Message I get when attempting to run the firmware update on a 2008 MacBook Pro: "ALERT: This software is not supported on your system."
So maybe not for *all* Intel-based MacBook Pro's?
Nice Digging work Longofest!
