Finder in latest Lion build 11A494a is 64-bit only application
$ file Finder
Finder: Mach-O 64-bit executable x86_64
It could be a mistake by apple or intentional way to force owners of first macbooks/imacs to upgrade.
For hackint0sh it means – end of sse3 emulation on top of sse2, and no Lion for pre-conroe cpus if Finder will use some ssse3 instructions (which all 64-bit cpus used by Apple have).
