Notebook Power Management

Hey All,
I bought a SONY VAIO PCG-FR130 not too long ago which uses the AMD XP-M
processor with PowerNow. So far everything has worked great except I'm a
little dissapointed with the performance of it on battery power. In
Windows XP I was able to get within the 2.5-3.0 hour range but with
Linux I only get about an hour and 50 minutes.

I am using the 2.4.21rc1 kernel with ACPI all patched up. Is there
something else I can be doing to extend the battery life?
