>Description:
The problem occurs in an IBM Thinkpad T41 with ATI mobility 9000 card.
When the xorg dri module is loaded (that is when an uncommented Load "dri" is present in the xorg.conf file) doing suspend (acpiconf -s S3 or Fn-F4 in a thinkpad laptop) cripples the X server (it shows random colorful dots located mostly on the top of the screen) and it locks the computer completely.
When you remove the dri line in the xorg.conf file the computer almost survives the suspend. However the moused dies.

Please please please guys fix that before the release! 
>How-To-Repeat:
Use ATI mobility 9000
Add Load "dri" in xorg.conf
Suspend with acpiconf -s S3
Resume (press any button) to see a funny X server!
