yes, i remember it, peter -- frank (author of amiga port) told me some other atari guy contacted him but i had absolutely no idea who it could be ;)
about your idea -- i really doubt it will gain some speed. now you use chunky buffer, you write byte pixels there so it's the fastest possible way. now, c2p is copyspeed, i.e. is as fast as copying using move.l (a0)+,(a1)+ so there's no advantage of using non-c2p handling.
another thing is checking this (and only this) using comparative c2p... that's quite nice idea (not whole panel gets updated every frame).
