3.3 kernel from TI landing teams and powervr problems.

There is an omap_drv.so which should be the xorg driver to load.. it
will attempt to load (if present) omap_pvr_drv.so as a submodule for
EXA accel.  I'm not entirely sure why it is named pvr_drv.so in your
filesystem, but from list of symbols it seems to match what I would
expect to be omap_pvr_drv.so

BR,
