Instead of getting all of the hardware variables, and grepping for a specific variable, simply use sysctl to get that specific variable.

command:

sysctl hw.cpu64bit_capable

return:

hw.cpu64bit_capable: 1 (or 0 depending)

This only indicates whether your Mac is capable of running 64-bit applications. It says nothing about whether you can run Snow Leopard’s 64-bit kernel.
