Description of problem:
When running glxgears after resume from suspend on a system equipped with an
ATI Radeon X800 SE (R430), all I get is a black window. Moreover, it does not
react to keyboard input, namely pressing <ESC>. The application windows just
stays there, even after pressing <ctrl-C> in the terminal window from which it
had been launched.

Version-Release number of selected component (if applicable):
mesa-7.10-0.29.fc15

How reproducible:
Always.

Steps to Reproduce:
1. Run glxgears.
2. Suspend and resume.
3. Run glxgears.

Actual results:
Application window is black and does not respond to keyboard input.

Expected results:
Application window shows turning gears.

Additional info:
* Vendor bug reference https://bugzilla.redhat.com/show_bug.cgi?id=643700
* This issue is -critical- for GNOME3 which is using a GL based desktop environment. In this case, the desktop is -frozen- after resume from suspend making the system unusable. Only the mouse pointer can be moved. The system needs to be rebooted or switched to a non-accelerated window manager like metacity.
* Upgrading to mesa-7.11-0.20110315.0.fc16 has no effect.
* Issue is absent for driver R300 TCL DRI2.
* Installed packages include:
  - kernel-2.6.38-1.fc15
  - libdrm-2.4.24-1.fc15
