Functional test:

test booting with a live CD of each type --- a 32 bit only
capable processor will 'choke' on the 64 bit CD -- the 64 will
handle either. SO .. a 32 bit CD will boot on either type of
hardware


'Read the label' test

Once the unit is up with a 32 bit CD, inspect the processor
strings and verify at the vendor's

     cat /proc/cpuinfo



If it is a unit with a vendor provided 'build sheet' it may
call out the specific processor and stepping, but be wary here
--- some hardware manufacturer's disable capabilities the
processor has ... Laptops particularly may have a
virtualizaion capable processor, but such is disabled often
