2.6.16 on 32bit doesnt report the cpu speed anymore, but it still has the bogomips..
chrp_calibrate_decr doesnt seem to set ppc_proc_freq.

lemon:~ # cat /proc/cpuinfo
processor : 0
cpu : 604r
revision : 49.2 (pvr 0009 3102)
bogomips : 41.47
timebase : 20781060
machine : CHRP IBM,7046-B50
lemon:~ # dmesg | grep freq
time_init: decrementer frequency = 20.781060 MHz
time_init: processor frequency = 0.000000 MHz

While looking at generic_calibrate_decr(), cpu and fp are pointers.
