Dear Mr. Deutcher, thank you for will and readiness to help in this
problem!!

I am using radeon.gart=1024, it does not help.
Then I upgraded to Tumbleweed (3.11)
Glxinfo reports:

OpenGL vendor string: X.Org R300 Project
OpenGL renderer string: Gallium 0.4 on ATI RS600
OpenGL version string: 2.1 Mesa 9.2.2
OpenGL shading language version string: 1.20

Then I added radeon.dpm=1, there are no information about dpm or
powermanagement what so ever in dmesg (unlike 5850 card that I have). I
suggest dpm is not supported on this chip. Not great deal, but for
example, 5850 is unstable withOUT dpm in 3.11.

Lastly, of course I read all patches and responses from people in these
two bugs, and tested first switching from 256 VGA memory to 128 via BIOS
(only two options), it didn't help.

Then I appended "radeon.vramlimit=64" to grub2 kernel line, updated
grub, rebooted. Nothing changed. I attach the screenshot showing the
issue with gnome-shell corruption and the login triangle issue, that is
even more agressive when system comes out of hibernation.

dmesg | grep -i radeon says:

I will test the patch today.
At your will, I will give you remote login to the notebook for any kind of testing you so desire.

Title:
  [rs690m] [Gateway] Graphics corruption with ati x1200

Status in The Linux Kernel:
  Confirmed
Status in X.org XServer - ATI gfx chipset driver:
  Fix Released
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  [Edit]
  This bug has been around for a bit over a year now, and has gotten rather long, so this is a brief summary.
  There is a memory corruption issue that affects users of the rs690m, to varying degrees.
  For many most people, it makes the desktop unusable.

  Workaround:   *Note: This is a workaround, not a fix.  It will give you a usable system.
  [Natty]: Regression: This workaround now only provides 2d/software rendering, and one must either:
     * Choose choose the "Ubuntu Classic" session from the GDM Login screen
     or
     * Install the "unity-2d" package.  
    
  [code]
  sudo su
  echo options radeon modeset=0 > /etc/modprobe.d/radeon-kms.conf
  exit
  [/code]
  Note that this doesn't totally fix the issue, but brings your desktop to a workable state.

  Freedesktop.org has dealt with one bug having to do with graphics corruption on the rs690m.  That bug has been fixed, but the issue of graphics corruption in general has not been resolved.  A new bug has been opened with freedesktop.org to continue pushing through the resolution of this issue.
