--- Comment #5 from Jason Vas Dias <jason.vas.dias at gmail.com> ---
OK, I tried adding 'radeon.dpm=1' to kernel command line:
fbcon=map:01 radeon.modeset=1 radeon.dpm=1 video=radeon:1920x1080 at 60e \
drm_kms_helper.edid_firmware=edid/1920x1080.bin
(I have copied a valid 1920x1080.bin to /lib/firmware/edid/1920x1080.bin made
by translating the EDID dumped by FGLRX to binary:

I attempt to get this loaded both by kernel command line argument
and in xorg.conf, but it never gets to that stage .
)
Now, with the radeon.dpm=1 kernel boot parameter specified, the
dmesg log produced by the command :
$ { echo ON >/sys/kernel/debug/vgaswitcheroo/switch;
echo DIS >/sys/kernel/debug/vgaswitcheroo/switch; sleep 1;
echo OFF >/sys/kernel/debug/vgaswitcheroo/switch; sleep 1;

The 2 copies of the vga_switcheroo/switch created by command were :
::::::::::::::
/root/vga_switcheroo_switch_at_X
::::::::::::::
0:DIS:+:DynOff:0000:01:00.0

/root/vga_switcheroo_switch_last
::::::::::::::
0:DIS:+:DynOff:0000:01:00.0
1:IGD: :Off:0000:00:02.0
And when the terminal finally returns it is still at:
0:DIS:+:DynOff:0000:01:00.0
1:IGD: :Off:0000:00:02.0
which is nonsensical, because we know the i915 never relinquished control
and is being used.
So it looks like the Radeon driver thinks it has power control, but doesn't.
Does anyone know what 'DynOff' state means ?
Or how to transition from 'DynOff' to 'Pwr' ?
The 'ON' command to vga_switcheroo/switch does not work in state:
0:DIS: :DynOff:0000:01:00.0
1:IGD:+:Pwr:0000:00:02.0
to transition DIS from 'DynOff' into 'Pwr' state.
