Are you volunteering? :) One other, perhaps easier task might be to write a TurboChannel front end for the AMD driver. Supposedly the AMD 53c974 and NCR 53C94 are pretty much the same chip. The NetBSD esp driver might be a good place to look for clues. Until the esp driver is ported, or someone makes the AMD driver work with those chips, you'll have to boot the machine diskless.
