I am not thinking of VGA graphics, but VESA... First of all because I 
use 800x600.

There are very good drivers that autodetect all existing video hardware. 
That is basicaly what I have in mind.

My point is that Dosemu works very well in grahic mode under X, *better 
then any other simulator* so my idea is just to use that as a basis for 
a dos system.

Thare is also a few advantages: Linux network support and better 
filesystem. I have noticed that compiling a program under dosemu is 
*faster* that with plain DOS on the same machine !!!
