2) successful installation of .NET 2.0 Framework
3) "l_intl.nls" copied from windows installation to wine system32
4) PEB loader lock patch from http://bugs.winehq.org/attachment.cgi?id=9195
5) true type fonts correctly installed for native gdiplus (comment #2)

Ok, what happens?
Well, in native code it checks if the user is "interactive" by using
GetProcessWindowStation() and GetUserObjectInformation( USEROBJECTFLAGS) API.

Unfortunately wine has this special flag not set (if not set by WindowStation
creation or SetUserObjectInformation API)
Attached is a patch which fixes this.
As soon as a desktop gets created, this flag is set (e.g.  winstation->flags |=
WSF_VISIBLE)

At this point, .NET gui apps _might_ start working.
---------------------------------------

Stay tuned, more goodies to come ...
