I don't think it really means much because if it's all host DMA memory
outside of the range the lnc device can access, then it will look
perfectly initialized like the driver expects it to -- because it is
pristine! What I would do would really quick change the driver so that
where there's BUS_SPACE_MAXADDR_24BIT, you replace it with a TUNABLE
and then try out some different maximum values via the loader. I bet
you'll find it stops working if you make it too big, and starts working
if you make it small enough.
