OpenGL acceleration with Intel HD 3000

I'm having the same issue with GPU on my MBP 2011 and was using the same solution as yours (plus additionally disabled AppleIntelHD3000Graphics.kext). Saving money for motherboard replacement (or the new Haswell MBP whatever)…

I'm able to play most of videos with Miro player.

Although, I'm starting to have difficulties with my eyes since it's not possible to control monitor brightness anymore…

The Intel HD 3000 was used as single card also in some Mac Mini configurations.

You can start by these links:

and

but I strongly suggest to post your question on insanelymac forums, probably there you will find people with better knowledge about kexts and possible alternatives for your case.
