cat /proc/cpuinfo

Look under flags for "lm" (= 64 bit) or "tm" (32 bit).

Issue a uname -m from the command line and it should report something like x86_64 or ppc64 for 64 bit versions

Sorry, "tm" was a typo, I meant to write "pm" (for "protected mode", 32 bit), a flag which is not mandatory.

"lm" ("long mode", 64 bit) is correct, however!
