Suspending MM10 (again)
If you end up using pm-utils for power management (make sure you DO NOT install acpi-functions), drop a file called ’sharpmm10′ (or any name you like) into /etc/pm/config.d, which reads as follows:
ADD_PARAMETERS="--quirk-dpms-suspend --quirk-dpms-on" SUSPEND_MODULES="ath_rate_sample ath_hal ath_pci"
gnome-power-manager kicks of pm-utils.
I hate power management in linux.
