I tried uname -a, but I don't understand the output: Linux (hostname) 2.6.28-19-generic #65-Ubuntu SMP Thu Sep 16 14:14:28 UTC 2010 i686 GNU/Linux
I have an i686 processor, but I do not know what that means with regard to the 32-bit or 64-bit issue. I looked at the wikipedia page for i686, but that didn't contain any useful answers. I tried grep lm /proc/cpuinfo, and it looks like I do not have the lm flag. I see something called lahf_lm, but I suppose that's not the same thing.
