They do suggest that, but after looking into it, it seems like a small
mistake in the driver that won't actually affect operation.

This procedure does suggest some kind of interrupt problem though.
IRQ 11 makes sense; it's shared with yenta.  I don't know why you're not
seeing the nsp32 interrupt handler run though.
