Thanks, missed the '.0' part.

Right, that needs work. Maybe when buffers are flipped omapfb update can be called. If I understand it correcly omaplcd.ko implements device independent framebuffer for the rest of powervr code and now implements two 800x480 'flipbuffers'. So in theory omaplcd.ko is the only device specific part we need to change, correct?

Is it known what part leaks, kernel side or userspace (mbxdaemon or whatever)?

well when screen is off, the hardware (lcd panel, epson controller, omap display controller) is off and maybe powervr driver (omaplcd.ko part) is not aware of that and blindly writes some dispc registers? Hmm, I need to check whole omapfb/rfbi/blizzard code again, I guess powervr's omaplcd.ko assumes too much and expects omap display controller to actually drive the display and messes with lot of its registers, this seems wrong to me but how comes it even works as is?
