For this fix to work you must use the RIGHT firmware, if you copy the blog post exactly you will get the firmware for the 5,2. If you don't have a 5,2 then it won't work.

For example, if you have a MBP 5,5 then I would EXPECT that you should try downloading the following firmware update package:
http:// support. apple.com/ downloads/ MacBook_ Pro_EFI_ Firmware_ Update_ 1_7_

Good luck,
