I have a theory... Maybe there is a race condition between the intel and
ati driver involved here? My notebook starts up in two seemingly random
configurations, or three including the radeon crash:

1. X server is on VT8 -> unable to unload radeon module because it is in
use (by some framebuffer I guess). I am also unable to switch to
consoles VT1-7. If I use vga_switcheroo to switch to integrated gpu in
this mode then radeon crashes.

2. X server is on VT7 -> I can unload the radeon module and use the
consoles VT1-6. vga_switcheroo works and I can also use acpi calls to
turn off the gpu.

3. The radeon driver crashes.  Forcing reboot through RSEIUB.

This makes it difficult to control the temperature since I cannot know
if the radeon module is in use or not (i.e. I might or might not be able
to use the vga_switcheroo, or unload the module and use a specific acpi
call to shut of the gpu).
