Okay, here's a half-assed fix.  With this patch applied, if you try to
unload a module while you're opening it's dev attribute, kernel will
oops later when the file is accessed or closed later but it should fix
the bug winecfg triggers.  I really dunno how to fix this the right way
in the stable kernel.  Better ideas?  Anyone?
