The machdep.maxspeed was introduced to scale up and down the hw.setperf
parameter on this system.
The Zaurus normally operates at 416Mhz, the sysctl.conf contains the line
machdep.maxspeed=520 on the Zaurus.
I was going to set the maxspeed at that (worked on previous kernels) and the
setperf value at 80 and vary it to 100 when I was running a build (along
with atactl /dev/wd0c writecacheenable - I'm using a SanDisk Ultra III which
provides write cache, can't remember if the Microdrive did).
Any more thoughts folks?
