Question: Does anyone know of an EFI downgrade for user on 1.8? I have found a 1.7 to 1.6 downgrade, but once on 1.8 this downgrade no longer works.

Background: After upgrading to Snow Leopard, and installing the EFI 1.8 update (as recommended by Software Update), I have lost the ability to burn discs. This also includes when using external burners and when booting into Vista using Bootcamp. Other seemingly related problems to the EFI I have are, chronic overheating, random temporary beachball lockups, longer boot times. These 'other' problems have been solved for other users who experienced these problems on EFI 1.7, but were able to rollback to 1.6.

I am looking for a solution that does not require sending my computer back to Apple.
