Hello,

here's something to play with:
ftp://ftp.netbsd.org/pub/NetBSD/misc/macallan/shark/stuff.tar.bz2
this tarball contains a kernel and a wsfb driver for XFree86 ( both 
- -current )
this will give you:
- - a console which runs in 1024x768 at 75Hz in 16bit colour
- - very fast vertical scrolling
- - X in 16bit colour ( don't forget DefaultDepth 16 in XF86Config )
- - X with some acceleration ( namely blits, fills, offscreen pixmaps and 
a hardware cursor )
known issues:
- - the text cursor looks funny ( because the text cursor is a sprite 
which sits in video memory which gets overwritten after a while )
- - when switching consoles the display position will likely be off by a 
couple lines

All this requires a rev. 5 shark, one that has an IGS 2010 graphics 
controller.

If you have a rev. 5 shark please play with this and tell me if it 
works properly.
Things to watch for:
- - missing characters when scrolling. I think I fixed the problem but I 
can't be quite sure yet.
- - occasional blank lines that should contain text. See above.
- - artifacts in X, for instance when moving windows around.
- - does the mouse cursor in X look right?
- - are there funny video artifacts on the console? Like some sort of 
vertical divide with stuff left of it being repeated right of it with 
plenty if jitter in between? Video output should be stable, apart from 
the known hardware issues ( like 'swimming' when IO's going on )

have fun
Michael
