MacBook Pro 1.5.1 update
Apple today released its MacBook Pro EFI Firmware Update 1.5.1, which it says provides fixes several issues to improve the stability of MacBook Pro computers. The update revises a recently-issued MBP firmware update that came alongside similar updates for most of its other Mac families, including the MacBook, MacBook Air, and iMac computers -- as well as a specific MacBook Air Bluetooth update -- and also comes with updated version of the Firmware Restoration CD 1.7. "After the firmware is successfully applied to your Mac, your Boot ROM Version will be: MBP21.00A5.B08 or MBP31.0070.B07," the company notes.
The version of the Boot ROM installed on your computer can be confirmed using System Profiler. To complete the firmware update process, users must follow the instructions in the updater application (/Applications/Utilities/MacBook Pro EFI Firmware Update.app), which will launch automatically when the Installer closes.

What would have been useful is a little sentence on which versions of MBP's this is for.

This is an update to the recent update. It seems the recent update was causing machines displays to blank out. I assume this is a fix.
The versions are in the boot ROMs: MBP21 = Version 2 MBP's. MBP31 = Version 2 MBP's.
When you install the new fix, the number of your boot ROM will not change, if you installed the recent update, but you will be informed that the EFI has been updated.

Should have read:
The versions are in the boot ROMs: MBP21 = Version 2 MBP's. MBP31 = Version 3 MBP's.
