Well what we did for droid4 was take the last know firmware and
make the linux_openpvrsgx driver use the generic pvr-drv.c with
an old version of the TI SDK. Since then we have a newer userspace
blobs from TI, but with no X11 support and still missing at least
one PM related config option.

Heh well my personal goal with time and motiviation permitting is
to have at least some sgx drivers for devices like droid4 work with
kernel 2D acceleration and mainline kernel driver just like with
gma500 :)

My guess is that any 3D related open soruce work done on the
gma500 driver can also be shared by the pvr-drv.c later on.
