Linux may or may not have this info - my Slackware does not seem to, but it does have enough processor information () to search the web for that particular processor's attributes. If you have Linux running, will also work. Freebsd's dmesg at the "Features" and the "AMD Features" you cited will contain that info, and yes, that "LM" means long mode, or in other words, x86_64.
