The popular commands are:
# isainfo -kv
# uname -a
# psrinfo -v
# isainfo -b
# arch -k

An E450 is a 32/64 bit capable system.  In my case, it turns out I am
booting 64bit and running a 64bit kernel.  Darren pointed out I would have
had to explicitly refuse 64bit support at installation time.

Thanks to all who replied so quickly!
