3On linux platforms, grok /proc/cpuinfo for the CPU/vendor info.
4
5Prob not suitable for upstream seeing as how it's 100% linux-specific
6http://lists.gnu.org/archive/html/bug-coreutils/2005-09/msg00063.html
7
8Patch originally by Carlos E. Gorges <carlos@techlinux.com.br>, but
9heavily reworked to suck less.
10
11To add support for additional platforms, check out the show_cpuinfo()
12func in the linux/arch/<ARCH>/ source tree of the kernel.
