There's probably a better way, but grab x86info, build, run as root. http://www.codemonkey.org.uk/projects/x86info/ If you're on intel and you have em64t in the "Extended feature flags", it supports the Intel 64 bit extensions. If you have the cpuid kernel module (CONFIG_X86_CPUID), you can get some more info out of the processor.
