Linux may or may not have this info - my Slackware does not seem to, but it does have enough processor information (<dmesg | grep -i intel>) to search the web for that particular processor's attributes. If you have Linux running, <lscpu> 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. A decent explaination is here: http://unix.stackexchange.com/questions/43539/what-do-the-flags-in-proc\ -cpuinfo-mean
