That might indeed make a big difference. The status for the GTA04 (OMAP3) is that we have a free kernel driver but it does not work (except for a 3.8 kernel where it works). Still unsolved are the OpenGL libraries and the microcode blob for the GPU.

AFAIR the last package by TI was for 3.14 but not for mainline but a TI kernel with additional infrastructure. We carry along and rebase the code every now and then: http://git.goldelico.com/?p=gta04-kernel.git;a=shortlog;h=refs/heads/work/letux-base/pvr http://git.goldelico.com/?p=gta04-kernel.git;a=shortlog;h=refs/heads/work/letux-base/hns/gpu/pvr-v4 but nobody could get it working. For a Pyra-Phone it would be much better. The SGX544 drivers seem to work. At least some guys testing the Pyra were able to demonstrate it. I do not exactly know what they did hack and they were not much interested to help me learn... Anyways there are Pyra videos of 3D games.
