set the CPU 0  0%
to something between
                 0%
and                100%
and let the             userspace
governor decide which speed to use in between. It's much easier with the
2.6. sysfs interface -- one of the reasons I'm not really too excited about
the cpufreq backport for 2.4. [besides, I _only_ use 2.[56] kernels...]

Probably a BUG I introduced in the latest backport. Hopefully I'll have
the time tomorrow to update it. In the meantime: what does /proc/cpufreq
tell?
