ATI Radeon power management disabled after resume

[m.ehinger at ltur.de]

I already ask these guys, but no annswer yet.

BTW, it's the same behaviour without X. After a reboot without ever X being started, temperature of the GPU is about 45 degrees
centigrade ( from acpi_ibm). Then i do a suspend and a resume the GPU temperature go up to 55 degrees centigrade and stays there
(until next reboot or X starts with DynamicClocks).

thanks

Maik

I think Xorg should handle this.  Unless the radeon exports some Dx
state control via ACPI, only device-specific extensions like
DynamicClocks can control the radeon.
