The most reliable thing for me is

`uname -m` (to tell me the kernel running)

`grep "model name" /proc/cpuinfo` (to tell me the CPU installed)

On my Mandriva 64-bit system, `uname -p` correctly identifies the
processor hardware but on a 32-bit Ubuntu box the same command returns
`unknown`. So it can't be reliably trusted.

(I don't have a 64-bit system running a 32-bit kernel so I can't exactly
test this scenario using the above commands. Maybe someone else here can
confirm or deny the utility of this combination. YMMV)
