It's preferred to be nocona for 64-bit support (EMT-64 support to be 
exact) and prescott for 32-bit only support. There should be a core2duo 
CPUTYPE rolling around the corner in the near future IIRC, but that will 
most likely be in gcc 4.3, which I believe it slated for being stable 
1~1.5 years from now.
