there is dynclk that is same ClockGating in UMS xorg.conf.

KMS power management is still in development and quite unstable. First
version is in 2.6.34-rc1 but it has quite a few hard lock and GPU
freeze problems.

Of course it would be nice if there was sysfs files to set the power
management options from user space but that would need some coding.
