Maybe someone with sufficient experience in porting drivers from
XFree86 to Xorg could comment as to

That would be a definite "either".

For a bitmapped display (*) by the time you have provided a wsdisplay
driver for console use I believe you pretty much have everything
required for Xwsfb to run directly against it. The exception would be
for systems with unusual bpp mappings (which possibly rings a bell for
Michael - would it make sense to suggest a "reference" graphics driver
for people unfamiliar with wsfb requirements to read?

Granted, but those are the users most likely to be wanting the most
out of their systems, so while they are collectively not more
important than those with standard amigas they arguably count for a
little more than a strict percentage :)
