Thanks Timothy, this makes things much clearer. I have found "lm".

Best regards,

Dear Peng, 
Yes, indeed, Lenovo X200 and X301 laptops have Core 2 Duo processors
which support 64-bit operation.   From Linux you can determine this
using /proc/cpuinfo (look for 'lm', for 'long mode').  
Booting a Barrelfish image on such machines is exactly the same as on
a regular desktop.
