Hi John,

I could have sworn I pushed this as a patch some time ago but it must have
got lost. 
This is the PowerVR init script we have been using for some time without
issue on the Beagle and Pandora.

It supports start/stop/restart/force-reload and modprobes the modules rather
than the insmod/find combo. 
Other than that it is comparable to your patch.

One other note is that you will need to bump the PR on the libgles-omap3_*
recipes (esp. 3.00.00.06 as that is the one in common use) so that the new
script gets baked in.

Regards,

John Willis
