Try with my latest fix. I think now the problem is that a proper VGA 
emulation is needed. I plan to add it soon by using an SDL wrapper.

My only problem is to choose the right SVGA board to emulate (plain VGA 
is not suffisant to get proper graphical display). I have the following 
choices:

- Bochs VBE (easy but limited to 8bpp)
- VMware virtual SVGA (easy but potential driver license problem)
- Intel i810 (there are good docs but the acceleration is complicated)
- Another SVGA card ????

I am interested by any opinion on that matter!
