Weird Centrino throttle problem

[inhotep]

WHen the power management is set to Max Battery, the mhz jump from 598 to 794, or to 1500mhz, it does not stay at a fixed mhz. This has never happened before. ANyone have any input on this?
I want the throttle to be as low as possible while on battery.
I have also seen Centrino 1.3-1.6ghz that can go as low as 274 mhz. How can i do that with my machine?
Nothing i can do in the bios.

Thanks

Gateway 4520gz (320M), 1.5ghz 1m L1, 2x256 pc2700, 855gm/gme (this is what sandra and 3dmark2002,2003 shows), which gms do i have? err. 7200 rpm 40 gig hitachi HD. SP2

I thought all pentium m's, whether banias or dothan can only be throttled down to 600Mhz.

it can go lower.
