[PATCH] Add tainting for proprietary helper modules 

Kernels that have had Windows drivers loaded into them are undebuggable.
I've wasted a number of hours chasing bugs filed in Fedora bugzilla only to
find out much later that the user had used such 'helpers', and their
problems were unreproducable without them loaded.
