We have been looking in to loading this driver under ReactOS and all of
the functions are implemented but it still returns STATUS_UNSUCESSFULL.
I think that the imports of "PsGetVersion and NtBuildNumber" might have
something to do with it. The driver works under my Windows NT 4 laptop
but not ReactOS. We may just have to hard code the values to match NT 4
and it could work.

If we can get it to load on ROS it will be up to you guys to figure out
a way to adapt ROS+WINE to play nice together. =)

Thanks
Steven

the driver reads the system's version, build number and service pack, and 
fails to load on an unknown platform, but it otherwise ignores the 
information. Furthermore, its runtime requirements are very limited - I 
estimate an evening of work at most to run it on Wine, since we already have:
  - a PE loader
  - support for SEH
  - a DDK

I believe this is the case
