[Bug 555943] [NEW] [lucid] [M92 LP] blank screen on Mobility Radeon HD 4300 with KMS enabled

[Mathieu Trudel]

Public bug reported:

On boot with a daily image (tested with ubuntu-server), the screen
remains blank at all times. Disabling KMS with "radeon.modeset=0" is a
workaround that will let the text on a console be displayed correctly.

Sorry there is little information, but as this was tested on ubuntu-
server, xserver-xorg is not installed and I can not immediately provide
X logs.

Attaching dmesg with and without modesetting enabled, as well as the
ouput of 'lspci -vnvn', /proc/version_signature and 'uname -a'.
