If you have a first generation MacBook Pro and haven't run Software Update yet (yes, that would be me too!) you should run it right now not only to get Security Update 2006-007, but also the MacBook Pro EFI Firmware Update 1.2:
This EFI Firmware Update fixes several Boot Camp, start up, and wake-from-sleep issues on MacBook Pro computers.
After the firmware update is successfully applied to your computer, your Boot ROM Version will be:
MBP11.0055.B08 (MacBook Pro 15 inch)
MBP12.0061.B03 (MacBook Pro 17 inch)
If you'd rather download directly, click on the links above to visit the download pages.
Personally I haven't had any of the aformentioned issues with Boot Camp, startup and wake-from-sleep modes, but I'll be applying anyway.
