I don't think "Wine is too simple yet" is correct.
Wine will never (?) support VxDs (it's simply not possible),
and I guess this is a VxD issue...

You could try to get something via VMWare (that seems to work pretty well
in some cases) or maybe try the VxD monitor from www.sysinternals.com
(not sure whether that'd be able to help, though...)
