Well, I don't know how I can prove the hardware I am using:

# sysctl hw.model hw.machine
hw.model: Freescale e5500 core
hw.machine: powerpc
# getconf LONG_BIT
64
# grep -i cpu /var/run/dmesg.boot
cpu0: Freescale e5500 core revision 1.2, 1995.00 MHz
cpu0: Features cc009100<PPC32,PPC64,FPU,MMU,BOOKE,ARCH205,ARCH206>
# uptime
