[ltp] 390X to 650mhz SpeedStep

[Bert Haskins]

I purchased a MMC-2  650 to install into one of my 390X TPs.
I'm wondering if any one on this list has "been there, done that" or
has heard of anyone else doing this.
I don't think that there is any form of support for high speed in the bios.

The system defaults to battery mode of 500mhz.
Does linux (any distro ) have any support for kicking this up to 650?
Google only seems to know about (enhanced speedstep).
Thanks,
    Bert
