Ok I found out where the problem is and why I need to define the folowing 
symbols manually like this:
\font\msbmx=msbm10 at 10pt
\textfont15=\msbmx
\mathchardef\subsetneqq="3F24
\mathchardef\subsetneq="3F28
\mathchardef\supsetneqq="3F25
\mathchardef\supsetneq="3F29

I'm using the following setup:

\definetypeface[modern][mm][math][modern][ams][endocing=\defaultencoding]

because in this connection the following part produces the nicer output, 
or it there a way to the the dstroke environment behave like in the math 
under mant?

\definefamilysynonym[default][doublestroke][mb]

\def\dstroke {\fam\purefamily {doublestroke}}

here the Symbol for natural Numbers is produced like ||\|
and not like |\\|

hope the ascii-Art is readable...

Greetings Martin
