You need to stubedit the program which needs ring-0 so that the default 
DPMI server is CWSDPR0.EXE instead of CWSDPMI.EXE.  (You could of course 
rename CWSDPR0 to CWSDPMI, but that's less convenient if you need to run 
other DJGPP programs on the same machine).

CWSDPR0 disables virtual memory, so the answer depends on how much memory 
do you have physically installed on the target machine.

The compiler and linker, of course, can use CWSDPMI, so compilation isn't 
the problem; running the program is.
