heh, This doesn't apply either. Or is this to be done before the patches
are added?

Anyway, I did find the two konfig references:

...

          This is purely to save memory - each supported CPU adds
          approximately eight kilobytes to the kernel image.  For best
          performance should round up your number of processors to the next
          power of two.

source "kernel/time/Kconfig"

#
# Timer Interrupt Frequency Configuration
#

...

config GENERIC_TIME
        bool
        default y

source "kernel/time/Kconfig"

config CPU_SPEED
        int "CPU speed used for clocksource/clockevent calculations"
        default 600
endmenu

...


I'll apply your patch in quilt and then make the proper change. Which
Kconfig do you want gone?
