Just testing with ACPI power saving without amd_disconnect. I'm back to 45°C cpuwise, but without 14% background load from apmd. Looks nicer in gkrellm, but no measurable/noticable difference otherwise. Will stay at amd unconnected ACPI power savings for now.
Most important: vlc (CVS 0.2.92) is happily working again.

Would have saved me one reboot..
