Thanks.  Some comments:

     In V86 mode, the 386 operates in real mode but allows some programs...

I believe you meant to say "protected mode".

  That means programs like DOS can coexist with protected-mode programs. 

I don't think V86 has anything to do with RM and PM programs coexisting. 
perhaps I'm missing something in your reasoning.

  The memory management unit (MMU) on the 386 supports virtual memory

This is inaccurate: VM is not implemented by MMU, but by software that hooks
the Page Fault exception and pages memory in and out as needed.
