It reports PowerMac7,3:

    $ cat /proc/cpuinfo 
    processor       : 0
    cpu             : PPC970FX, altivec supported
    clock           : 2700.000000MHz
    revision        : 3.1

    detected as     : 336 (PowerMac G5)
    pmac flags      : 00000000

At the moment several people are working on the machine setting up
services so I haven't been able to reboot to try the 2.6.12.3
linux-stable kernel yet.
