    I haven't been keeping track of cpufreq lately, but I added a check into
    my est driver a long time ago to make it return EBUSY if the TSC is being
    used as a timecounter. This is important because otherwise all sorts of
    Bad Things could happen when the clock stops running at the expected rate.
