Specifically what information can you rely on in that info will be a reliably indication that your particular Centrino branded cpu is 64bit capable? is there a particular flag that marks it as 64bit capable or do you have to know something about the specific cpuid?
"lm" is the flag; if it is there, your CPU supports "long mode" aka 64 bit mode.
I guess you could be more specific (in case somebody made a flag or another cpuinfo line with "lm" in it) with a:
grep '^<flags>.*<lm>' /proc/cpuinfo
