It certainly true that WDM/NT kernel-mode environment offers no built-in
facility for calling user-mode code directly or linking to user-mode DLLs
implicitly or explicitly.

However, before flatly claiming that this sort of thing is "impossible", you
may want to first read OSR's excellent NT Insider article, "Understanding
and Using Execution Context in NT Drivers"
(http://www.osr.com/insider/1996/context/context.htm).  Specifically, see
the section titled "Take It To The Limit".
