The esp driver hasn't been ported to CAM. 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.
