Comment 128 for bug 363238

I didn't know such a thing existed.

So I tried to add (blindly) radeon.modeset=0 to my kernel boot options, and strange things happens ;-)

- I had a bug during the boot process screen resolution that is now corrected
- My X display is corrupted, resolution is good but a green flavour color is added all over the screen
- GL is disabled,

Diff between Xorg logs about KMS shows :
with radeon.modeset=0 :
(II) [KMS] drm report modesetting isn't supported.
[drm] failed to load kernel module "radeon"
(EE) RADEON(0): [dri] RADEONDRIGetVersion failed to open the DRM
[dri] Disabling DRI.

without :
(II) [KMS] Kernel modesetting enabled.
(II) RADEON(0): KMS Color Tiling: disabled
