Hm.. I don't remember seeing that - my knowledge of 680x0 Linux comes from very very old ST format magazin! It shoul;dn't be *that* hard, the MMU is only involved in protect mode (or the equivelant on 68K - supervisor? I forget) memory paging for virtual memory, and if you have enough RAM then I suppose you don't need swapspace?
Excellent to hear about your raymapper :)) that was quick! Remember SubStation? an 8MHz ST/E can render 25 frames of gouraud shaded walls with light-sourced scaling sprites per second! I can send you technical infos on the Blitter chip if you need it.
