Excellent news!  Certainly makes my job a lot easier if you've already done
all the hard work to get the thing running :-)

I'm pretty sure we don't need the locking in these drivers anymore,
although I'm not 100% clear on the details.  Certainly all the
splusb()/splx() stuff disappeared with Julian's mega-MFC after 4.10.

Looking forward to it.
