I think that your configure file is correct (at least, not clearly wrong).
It just happens that either dosemu or the Win 3.1 SVGA driver can't 
access more than 256K of video memory, and this is what you reach at 
800x600, with 16 colors.
Going further (under DOS) needs special bankswitching techniques which 
seem unimplemented in dosemu 1.4.0 and/or the SVGA driver of Win 3.1.
Anyway, do you REALLY need hi-res with your Win 3.1 programs ?
If you really need to launch many programs at the same time, you can 
launch various instances of xdosemu and Win 3.1 at the same time ; 
they'll use different windows, of course. Just open a terminal, launch 
xdosemu this way :
$ xdosemu &
(type Enter)
and another dosemu:
$ xdosemu
You get two xdos windows, and you can launch Win 3.1 from each one.
Sincerely,
Robert
