    I would have to believe that "throttle" only works on Pentium chips. I
    am using 'powernow_k7' loadable module on my Athlon XP-M and that works
    excellent. You should be able to google for it, that way you:

    -- would have most recent version
    -- would know that I did not provide you with Trojan horse ;)

    HTH,
    Alexandre "Sunny" Kovalenko.
