Could you mail me (personally) more information on this ? I have been
doing xfree86 work for the glint driver, altough mostly for the pm3
chip, so i may be able to arrange something there.

I think the best idea is to print yourself a copy of pm2fb.c and
pm2fb.h, and then take another already adapted driver as model.
tridentfb and tdfxfb are maybe good examples.

I had some time the intention of writing a new API howto and to port
pm3fb, but i bought an AGP 8x motherboard and my old AGP2x pm3 graphic
card doesn't work with it anymore :(((

I think it would be best to restart from an already converted driver.
there is much less stuff that need to be done in the new API, and i
think it is easier to restart from scratch, using the old driver as
guideline.
