There is nobody else involved believe me.  I am just trying to do
the right thing.  This is not that big an issue as it has absolutely
no relevance to anything within that patch set.  I'm trying to
improve the overall experience of using KDB, which I've found most
helpful in the past to get around some very thorny issues, particularly
in regards to bringing up new hardware.  If blocking that usage by
non-GPL modules is what's required, then by all means I'm for it.

But understanding more of why the restriction is in place, would be
very helpful the next time I encounter it.

Thanks,
Mike
