I've read a couple articles about people upgrading minis with prerelease Meroms when the minis first came out, but most of those are short on details. Has any one heard of upgrading iMacs or Mac minis with production Core 2 Duos(Merom)? If so, does anyone know if the firmware in those machines work with all the 64-bitness and stuff, thus making it about the same as the expected Merom iMac updates?
