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…
