The bwtwo is unaccelerated monochrome, isn't it? In that case attaching 
a wsdiaplay is trivial, all you need to do is find out some information 
on geometry / data organization ( width, height, bytes per line, fb 
address ), fill in a struct rasops_info and that's pretty much it. 
Vesafb might be a good starting point.
