Not quite.  The R4000 and later CPUs support 64 bit operation, but the
Indy, O2, and IP22 Indigo2 are 32-bit machines.  To verify this, type
"uname".  32-bit machines return "IRIX" and 64-bit machines return
"IRIX64".  32-bit machines are unable to boot a 64-bit kernel or run
64-bit binaries, though they do gain a modicum of 64-bitness via the N32
