I've just had a bash at implementing something similar for the unichrome overlay layer, with some success. The same structure is appropriate in that case too so it would be nice to give the ioctl a more generic name (FBIO_FLIPONVSYNC?) and an number in the 'F' range (0x21?). What's causing me trouble at the moment is the fact that I've only got a VBLANK interrupt to work with and the VBLANK-VSYNC interval is too short to guarantee I can get the new buffer set up in time. When the machine is heavily loaded, it can miss and that gives a repeated field. Anyone got any bright ideas on this?
