As stated on the beta download page and README files: Lightroom 4 requires 64 bit addressing. Some of the first generation Mac Intel systems don't support 64 bit addressing.

Official answer from the Lightroom team:

"NOTE: On the Mac platform we needed to make ... a decision to end support for systems that are not 64-bit capable."
