Hello all

I had the same problems with centos 6.0 and a SandyBridge laptop (Dell 
Latitude E5420 i5 2410M)

you have to install the following from SL 6.1:
  - latest kernel (kernel-2.6.32-131.12.1.el6)
  - kernel-firmware-2.6.32-131.12.1.el6
  - latest xorg-x11-drv-intel (xorg-x11-drv-intel-2.14.0-1) with 
dependencies (xorg-x11-drivers)
  - latest mesa packages: mesa-dri-drivers, mesa-libGL, mesa-libGLU 
(version 7.10-1 at the moment)
  - latest libdrm (libdrm-2.4.23-1)

openGL and DRI now work. (for my laptop also screen brightness and 
suspend to RAM work ok)
