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

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.
