syncfb implements that, but it isn't real deinterlacing, just upscaling of
fields to frames and offset every second source field by a half pixel to
avoid bobbing fx.
afaik only newer ATI cards (rage128, radeons) has real deinterlacer, but
it is not supported (i remember some experimental support in old radeon_vid
kernel driver, but afaik it was not ported to vidix).

impossible without irq
with irq handler it can be done.
