I don't think you're allowed to do this. I'd suggest you simply have your
program go look in /proc/cpuinfo to get this sort of stuff. The kernel does all
this for you and stores the results. When you access the psuedo files under the
/proc filesystem you can get all kinds of useful info, without resorting to
horrid code. It'll also port to the Linuxes running on completely other CPUs.
