Firstly, sorry for the vagueness of the comment I am about to make.
While looking through kernel and freedesktop radeon bugs a while ago I
came accross a screenshot that matches the description in this bug. I
can't remember the exact hardware the reporter was using, but the
problem had been fixed with a patch. Unfortunately I can't remember
which kernel version had the fix, but it was before the currently-under-
development 3.6, so I suggest trying Ubuntu 12.10 "Qantal Quetzal" beta
2 which is based on the upstream 3.5 kernel.
Please let us know whether the problem occurs or not on Ubuntu 12.10
"Qantal Quetzal" beta 2.

Title:
Corrupt graphics on resume from S4
Status in X.org XServer - ATI gfx chipset driver:
Confirmed
Status in “xserver-xorg-video-ati” package in Ubuntu:
Incomplete
Bug description:
Binary package hint: xorg
I'm unable to resume from S4 on a Lenovo ThinkPad SL510 w/ ATI
Mobility Radeon 4570 (1002:9553). Upon entering S4, the graphics
become corrupt - it looks a bit like an X11 stipple or that
checkerboard that used to be the X background (though it's not just
B&W, there is some R/G/B in the pattern. The pattern is not as random
as static; it appears tiled, as if we're displaying tiles populated
with corrupt video memory.
On resume from hibernate, the BIOS logo is not corrupt and the (not-
corrupted) plymouth logo flashes for an instant. There are several
seconds of a flashing white cursor at the top left of the screen too.
Once X comes back I see the stipple pattern/corruption again. Both the
X and console sessions are corrupted. There is a separate corrupt tile
surrounding the mouse cursor (the cursor itself is not visible).
Moving the mouse cursor results in the mouse-tile moving around. The
machine is otherwise functional - I can (blindly) login to a console
on a VT and execute commands.
Syslog from the failed resume session shows errors from drm:radeon,
starting with:
Dec 19 14:36:49 ubuntu-ThinkPad-SL510 kernel: [ 1026.671568]
[drm:r600_ring_test] *ERROR* radeon: ring test failed
(scratch(0x8504)=0xCAFEDEAD)
Dec 19 14:36:49 ubuntu-ThinkPad-SL510 kernel: [ 1026.671570]
[drm:rv770_resume] *ERROR* r600 startup failed on resume
If I disable the radeon driver by adding, e.g., the made-up
'radeon.nofailboat=1' kernel parameter, the machine enters and resumes
from S4 normally, with no corruption upon either entering or resuming
from S4.
I've reproduced in both the stock 10.10 kernel and the daily natty
kernel (2.6.37-999-generic #201012200905).
