I did not solve this particular problem for PVR-350. You will
definitely need some sort of vertical retrace synchronization; I have no
idea how that works on that card. On nVidia you may choose the old
/dev/nvidia0 method (for old drivers) or the new OpenGL method (for new
drivers, though I'm working on solving a crashing problem).

It will certainly take me a few days; maybe not until next week. But
I'll get to it.
