To clear up a few points on go32 and DV/X:
  - DV and DV/X both support VCPI but VCPI does not make any
    note of how a client program is to collect hold and access virtual
    memory. VCPI states that the client and server both share a page table
    that mapps the first 640K of memory but if the server program is 
    supporting multiple clients then some of the first 640K must be
    remapped so that is is client unique. This means that the first
    640K of memory may not have virtual==real(boy did I learn this the
    hard way).

  - go32(aka gcc) can be made to run on DV/X, at least I have had some
    limited success. When I am able to assert with some assurance that
    my patches to paging.c work I will post them. alternatly if someone
    wants to check out my patches or has a burning desire to fix up the 
    few areas where I have not completly modified the code. I will be
    more than happy to send out a copy to them along with the comments
    indicating places that I know still need fixin.
