Throwing an OS X 10.5/PowerMac into the mix. Its a 64-bit PowerPC:

  $ machine
  ppc970

  $ sysctl -n hw.optional.x86_64
  second level name optional in hw.optional.x86_64 is invalid

  $ uname -m
  Power Macintosh

However, there are two interesting ones on the PowerMac:

  $ sysctl -A 2>/dev/null | grep hw | egrep 'machine|64'
  hw.machine = Power Macintosh
  hw.physmem = 2147483648
  hw.l2settings = 2147483648
  hw.optional.64bitops: 1
  hw.cpu64bit_capable: 1

And on a modern Intel with a Core-i7:

  $ sysctl -A 2>/dev/null | grep hw | egrep 'machine|64'
  hw.machine = x86_64
  hw.physmem = 2147483648
  hw.cachelinesize = 64
  hw.cpu64bit_capable: 1
  hw.cachelinesize: 64
  hw.optional.x86_64: 1
