I'm wondering if Wine supports Win16 under Linux x86-64 (even if Wine
is compiled 32-bit, if it works the basic infrastructure exists, at
least in the CPU)

Long mode (the 64-bit mode) has a "compatibility mode" that supports
32-bit and 16-bit code (I have no idea if it is real/protected mode
16-bit code...) which should be able to run the code. (See page 7
here: http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/24592.pdf
) It seems that the only reason Win64 does not run Win16 / DOS program
is the lack of a updated version of NTVDM and WOW.

OpenGL based DirectX 10 under XP, as under Wine. Even easy to get
OpenGL based DirectX 9 builds should be useful for people running
Windows under Virtualization.
