CONFIG_HZ is not broken, but the whole clock configuration is.
(I poseded something about it for 8260 earlier this summer)

Basic problem is that CLOCK_TICK_RATE which is used for setting up the
variables used for advancing the clock, is hardcoded to a value that
only makes sence for an i386. (it is default set at 1193180Hz which
happens to be the timer clock for timer1 on an i386 machine)
I do not believe CLOCK_TICK_RATE affects timekeeping at all on ppc or
ppc64 machines, but I could be wrong.  Can you show us where and how
CLOCK_TICK_RATE affects things?

Paul.
