Intel Sandy Bridge plus Nvidia GPU

[Ratin <ratin3@xxxxxxxxx>]

Hi I am trying to utilize hardware accelerated grpahics on a system with Integrated Intel GMA3000 graphics and NVidia GeForce GTX 460 on PCI bus and having some issues with loading both Xorg driver. I 
obtained and compiled sources for vaapi library (only for Intel, Version
 1.0.15), libdrm (V 2.4.37),  intel-driver (V 1.0.17). I enabled both 
PEG/PCI for the graphics in BIOS, specifying both GPUs in xorg entries 
and I got both the kernel mode driver to load. But as all the kernel 
mode driver loads,  followed by dri and dri2 X extension modules, nvidia
 X org driver gets unloaded. I think this is because dri2 is bound with 
intel but I am not sure why it would not allow more than one instance of
 X driver. Consequently I can not use nvidia driver to do any deHW accelerated decode/ndering (with its single instance it works).
 Atached are my Xorg logs and xorg.conf.

Here is my lsmod output :

Note: On a system with just nvidia driver (PEG only on BIOS, one entry in xorg.conf), drm_kms_helper and drm does not show up in lsmod.

Did anybody here successfully able to achieve this?

Thanks
