3.3 kernel from TI landing teams and powervr problems.

[Martin Ertsås]

Thanks to this, I got x running, problem is that I don't seem to have
direct rendering. First it complained that glx could not be loaded. When
adding the glx extensions from the xserver, I get some problems with
AIGLX. It sais that /usr/lib/dri/omap_dri.so could not be found. Is this
something I should have with these three packages, and I have not
compiled everything I should, or is it a fourth package which I haven't
installed?

Searched through the xf86-video-omap, and doesn't seem to build anything
but omap_drv.so, but it do contain a file omap_dri2.c. Should I let the
glx warning appear, and just ignore it maybe? Do the driver provide dri2
by itself?

Thank you so much for your help so far.
