It is quite new and was added to CURRENT too late to be adequately tested before the freeze to prepare for 6.2-Release. I suspect it will be MFCed fairly soon as the the freeze on STABLE should be thawing (or might already be doing so). I believe that acpi_ibm should provide some fan control, but the fan is really not much of a power sink. Make sure that you install radeontool from ports. It will let you turn off the display (not just the back-light) and the DAC for the video out. Try setting hw.pci.do_power_nodriver="1" in /boot/loader.conf. That will help (or crash the system). It works on my T43. You can then up the value to "2" or "3". I have yet to try "2", but "3" prevents by T43 from booting. Maybe the T60 will do better. Larger values result in more aggressive PCI power control. Finally, limiting the CPU speed while on battery is a winner. If you use Gnome, use the CPU Frequency Scaling Monitor and kill powerd. You can then manually set the speed. Try to enable EST. Add hint.est.0.disabled="1" to /boot/loader. It is not a win for my system, but it should be. Even though I have these on my T43, Windoows still stretches battery quite a bit. I get about 3.5 hours on FreeBSD and about 5 on Windows. -- R.
