   No, and ther most likely never will be.

   VxDs are more or less equivalent to Linux's kernel modules: most need
direct access to the hardware, must run in ring 0 (the most priviledged
level of the processor) and use a separate API (the DDK API rather than
the Win32 API). So Wine does not deal with VxDs.
   Maybe we should add a section in the Wine User Guide to list what
Wine does not do right after 'Wine capabilities':
