Changing multiplier settings on Pentium M

I've got a laptop with a 1.73Ghz Dothan (2MB cache) Pentium M. For speed stepping there is a minimum and a maximum multiplier - 13X (1.73Ghz) is the maximum, while 6X (~797Mhz) is the minimum. The processor seemlessly and quickly jumps between these as needed - it's so effective that unless I play a game or intentionally run a processor eating loop the CPU never stays at full speed long enough for the fan to become audiable, only long enough to complete the task at hand (render webpage, open document, calculate cells, etc).

In the interest of battery life and even lower temperatures, is there a (safe) way to reduce the minimum multiplier to something even lower then 6X? For example reduce it to 3X, causing the notebook to operate at ~400Mhz when I'm just typing.

For reference the laptop itself is an Asus Z33AE (M5AE/M5200AE)
 
Unfortunately, 6 is as low as it can go. The same is for Yonah and Merom and their desktop counterparts. You could decrease power further by forcing lower voltages for the different steps with rightmark clock utility. Gotta be careful though, too low of voltage and it will hang.
