Forwarding this bug for launchpad bug reporter smagoun:

Platform: Thinkpad Edge 14 AMD
Operating System: Ubuntu 10.10
CPU: AMD Phenom(tm) II P840 Triple-Core Processor
GPU: ATI Mobility Radeon HD 5000 Series (1002:68e0)
Kernel: 2.6.35-24-generic-pae (2.6.35.8)
xf86-video-ati: 6.13.1
xorg-server: 2:1.9.0-0ubuntu7

Summary:
Screen corruption (static/checkerboard) when starting X.

To reproduce:
Boot into the freshly-installed Ubuntu 10.10 OS. Notice the screen corruption
for about 3sec between plymouth and the OOBE. This is 100% reproducible on this
particular machine.

This isn't limited to the first boot, it happens on subsequent boots. It also
happens when switching from the OOBE to GDM/the desktop during login after
first boot.

I can't reproduce this if I disable the radeon driver, e.g. by passing the
'radeon.foo=1' kernel parameter
