dmesg with kernel 3.2.2

On my HP Pavilion dv7 6104eg notebook with kernel 3.3-rc2 I get the following
error:
----------------------------------------
[   10.341795] [drm] radeon defaulting to kernel modesetting.

----------------------------------------

I want to switch off the discrete Radeon GPU with vga_switcheroo when using
Linux as it gets quite hot and causes the fan to run permanently. This used to
work with kernel 3.2.2 without any problems.

Please tell me which additional information you need to resolve the issue!
