46932515ac Disable end of buffer fixup by default. New DDX does not need this, and 
since batch_len is unused by Linux driver, it seems that it is sometimes
gets passed wrong. This causes command buffer corruption and GPU hung.

Old GEMified DDX drivers that needs this workaround are not supported.

e27f871969 Add the code for new Intel GPU driver, which supports GEM, KMS and 
works with new generations of GPUs (IronLake, SandyBridge and
supposedly IvyBridge).

The driver is not connected to the build yet.
