Works fine with the OpenSource driver.

However that is the same, obviously the hardware does not support 16-bit luminance textures.
Which makes it rather pointless to use it, since 16-bit video will look still a bit worse than what libswscale creates and 10- and 9-bit will become 2- and 1-bit respectively.
Though if someone has a card where it works properly I'll add support for it anyway, no reason to let people with good OpenGL support suffer because others only offer crap.
