Bug#867701: Radeon HD 6450, black screen, cursor, no console

[Ivan Sergio Borgonovo]

Package: xserver-xorg-video-radeon
Version: 1:7.9.0-1
Severity: grave

Upgrading from 1:7.8.0-1+b1 to 1:7.9.0-1, PC boot but I get a black 
screen with cursor on the top left, I can't switch to console, xorg log 
just say

[    28.383] (II) glamor: OpenGL accelerated X.org driver based.
[    28.441] (EE)
[    28.441] (EE) Backtrace:

downgrading solve the problem.

I've a very very similar PC, same motherboard and slightly different 
video card (Turks PRO [Radeon HD 6570) that works.
