Dont know.. but just an idea.
With google "video acceleration linux" or ".. module", you can find for intel here https://wiki.archlinux.org/index.php/Intel
few information about it and which modules makes it.
So, I would
a) search my card name/model
b) search what module support the acceleration of it (lib32-intel-dri and others for intel cards in above link)
c) see if it is enabled in the xorg.conf (the Xorg.0.log should indicate it) in your pc
Just few thoughts. Hopefully it helps.
