Actually, the T60 comes with 32-bit (T2xxx) or 64-bit (T[57]xxx) 
processors:

Core Duo T2500 processor: http://ark.intel.com/Product.aspx?id=27236

I've seen T60 with Core or Core 2 selling here locally on craigslist. I 
figured, if I go with a 64-bit Core 2, I would just opt for the T61 with 
the slightly faster bus and supposedly lower acoustics. Plus they are 
selling for the same price.
