    Hrm. Upstream says there's a much enhanced version coming soon, perhaps
    then.

    The README.Debian says you need to mount sysfs in fstab (see below),
    but this isn't true for recent 2.6 kernels at least.

    Cool. I'll investigate when I get time, but I suspect it's not harmful to
    have it in fstab since I'm up to 2.6.7 now and haven't had a problem.

    Package: powernowd
    Version: 0.90-2
    Severity: normal

    The README and the man page both state that powernowd scales voltage
    ("Daemon to control the speed and voltage of CPUs"), which it does not (regrettably).

    The README.Debian says you need to mount sysfs in fstab (see below),
    but this isn't true for recent 2.6 kernels at least. Since 2.6.4 I've
    been running with no such definition in fstab and /sys works fine.
    I just installed 2.6.7 on a new machine and /sys got created automatically.

    Thanks for the good work -- powernowd works great! Pity about the absence
    of voltage scaling though.

    Cheers,
    David

    Out of date information from README.Debian:

    You also need to have the sysfs file system mounted, so that the daemon can find the interface to the frequency scaling support in the kernel. If that isn't already done, mkdir /sys and add an entry to /etc/fstab that looks something like this:

    sysfs /sys sysfs defaults 0 0
