The dmesg with 2.6.36 kernel

Hello,

I've got a strange bug since I've installed the new 2.6.36 kernel. KMS
configure my screen with the right resolution, but the display doesn't seem to
fit the actual screen size. When I look at the properties into the screen OSD,
it shows that it works at 1920x1080 (1080P). As a result of this, the
resolution is correct but the display is smaller than this, so I've got black
lines and my display is blurred.

I could reproduce the bug on two different screens, two different radeon GPUs
and with two different configurations of the kernel.

As I use an HDMI connection, I tried with the VGA one but it doesn't permit me
to display such a large resolution.
