You could try powertop.
For me (Lenovo T60p) settings seem to lose effect after a resume from suspend (YMMV).

I'm not sure if this is applicable to your kernel/laptop, but I managed to double my battery life with the following kernel parameters added to my /etc/lilo.conf.

Code:

append=" vt.default_utf8=0 acpi_osi=Linux acpi_backlight=vendor pcie_aspm=force i915.i915_enable_rc6=1 i915.lvds_downclock=1"
