I don't understand this, perhaps because I'm not an OpenWindows user.
Are you saying that a subset of OpenWindows requires dynamic
device driver support, but the whole of it doesn't?
The real question is: can you link these drivers in in a permanent fashion
when you build your 4.1.X kernel, and then disable all dynamic loading
and unloading, or does the act of loading/unloading these particular
drivers have an active side-effect that means you can't do this?
