    If you have a laptop you could use powertop to check it indirectly on battery...

    Agd5f posted a patch that prints a line in the log every time the clock switches. Don't remember if it was here or on IRC though...

    I am talking about the fglrx powerplay. Sorry for the confusion :-)
    Haven't tried the new ati rewrite yet. Will do when we have better 3D support for r600 :-)

    This is a Mobility HD3650 by the way, in an Asus F8Va. Could this be a BIOS issue? If I remember, vesa driver didn't work either (X did not start).

    Yeah, I think Overdrive is a desktop fglrx option, not mobility. Not 100% sure about that though.

    The new power options are for the radeon driver, so aticonfig won't work (it's part of fglrx). The power management options for radeon are set in xorg.conf.

    If you're going to run the radeon driver, you'll need to uninstall fglrx first and reboot to make sure the fglrx kernel module isn't running. Some distros will take care of this for you automatically. If you haven't run radeon for a while then you probably don't have the new drm with 6xx/7xx support -- get that from the 6xx-7xx-support branch of mesa/drm. Finally you'll need the latest radeon driver from git.
