au1x00 power management
PATCH 1/1 au1x00 power management
hello!
this is a trivial patch which enables the experimental power management on au1x00. while it does not add anything substantial it makes it working again by resolving some naming issues - resulting in about 50% less power consumption on my machine.
regards,
bruno
