So, I have already someone from Berlin who is going to give me exactly these three boards for kernel development and testing \o/. > For CyberVision 64, CyberVision 64/3D, and Retina/Z3, the amount of work > shouldn't be that big.

I will have my A4000 set up by next week, equipped with a Buddha, an X-Surf100 and the various graphics cards (one at a time). > However, in the mean time another S3 Trio / Virge driver was added, so it > may make more sense to add Amiga support to the latter.

Ok, I guess the next things to be done then are: - Michael Schmitz' ESP driver fixes for the Cyberstorm SCSI - Michael Karcher's xsurf100 driver - fixing Cybervision 64, 64/3D, Retina Z3 Might also be an idea to have another Linux/m68k meeting to get these things done :-).
