The stopping loading is purely because it now uses _GPLONLY symbols,
which is fine until the user wants to load a windows driver except for
the old CIPE driver. Some assumptions broke somewhere along the way and
the chain of events that was never forseen unfolded.

The problem is we do the dynamic link at module load time. We would have
to unlink the module if it tried to taint itself, which is clearly not
what the end user needs to suffer. Having the taint function actually
taint and printk + return a "Linked gplonly you can't" error seems the
better solution.

Really ndiswrapper shouldn't be using _GPLONLY symbols, that would
actually make it useful to the binary driver afflicted again and more
likely to be legal.
