the _go32_dpmi_* functions are still available in V2

The frame window at 0xd0000000 is *NOT* available under any DPMI, V1.x or V2.0
and cannot be made available.  You can access the vidram at 0xa0000 or a
linear extended memory buffer via many different methods.  The farptr
routines will always work, memory mapping and/or near pointers may work 
depending on the DPMI provider.
