Marked with < is not working kernel 3.2.0Marked with > works. kernel 3.0.0-12 / also works fine in LiveCD of Ubuntu 11.10

Hello all,
This e-mail is a continuation of my previews one regarding HDMI modeline output problems. So far with the help of Rodrigo Vivi i have manage to output the 1920x1080p at 60hz mode over HDMI to my AV receiver. (To fix my previews problem i inserted the EDID frame directly inside drm_edid.c file. So i dont read EDID from the AV i2c bus anymore. So the mode is always set correctly.)
The issue now is that the AV reports that the signal is not in RGB mode and the image shows some strange colors, specially on the white color (showing like greens).
Does any one has any idea if this is a problem on the EDID or inside drm/i915? 
All comments and help are very appreciated.-- Paulo Louro
