Package: linux-image-2.6.24-1-686 Version: 2.6.24-4 Severity: wishlist Current Linux includes support for force-enabling the High Performance Event Timer (HPET) on chipsets which do not advertise it in documentation or which disable it in BIOS, such as the ICH4 chipset used on many laptops. Using the HPET can significantly reduce power usage, in combination with nohz and C-states.
However, Linux will only force-enable the HPET if the kernel command line includes hpet=force. Please consider enabling hpet=force by default, so that a default installation saves the extra power without needing to edit bootloader configuration. All information I have seen on this option via LKML suggests that it only exists because force-enabling the HPET on many chipsets involves undocumented operations; however, as far as I can tell, force-enabling the HPET only happens on a whitelist of chipsets known to work.
