Link to original bug (#101447)

Description

At boot then uvesafb first picked up and then replaced with nouveau screen goes into distorted state. X can be run but nothing apperars on the screen except garbage. Switching between VT's works, but screen is still distorted.
Disabling all other framebuffer drivers in kernel config helped to solve this issue.
