The output of /proc/cpuinfo from this patch looks like the following:
[root@leaf7 ~]# cat /proc/cpuinfo
processor : 0
cpu : PPC970, altivec supported
clock : 1600.000000MHz
revision : 2.2 (pvr 0039 0202)
processor : 1

timebase : 199838713
platform : Xen
machine : CHRP IBM,8842-21X
Looks nice doesn't it :-) notice you see the machine type... ready for
the tree.
