I went to the nividia-page to maybe write the support-team when I have seen this changelog(*)
entry for the current version 375.20

 - Added support for FreeBSD 11.0-RELEASE

This version contains some other fixes that have to do with blank consoles(375.20) and vt stuff (375.10) as well. Even though they are not directly related to our problem.
I will try this version tonight and report back. Hopefully this will fix the problems ...
