I have successfully been using netbsd and X11R5 on a dumb PMAG-B cfb, via 
/dev/fb0    86,0      - and - /dev/mouse ---> /dev/fb0 

I tried out a sfb PMAGB-B and the raster console runs fine, but X looks 
like it is trying to write interlaced or something funny. Since the raster 
console works, I guess X should also, do I need a /dev/sfb0? and where do 
I locate the major/minor numbers?


cheers,
scott.
