--- Comment #26 from Edward Tomasz Napierala <trasz@FreeBSD.org> ---
Okay, I think I know what's going on.  I've added some strategic printfs, and
it looks like this:

iichid_attach: start
hidbus0: <HID bus> on iichid0
hkbd0: <DLL079F:00 044E:120B Keyboard> on hidbus0
kbd2 at hkbd0
iichid_intr_start: done
iichid_attach: done

What seems to happen is that iichid_intr_start() sets the power correctly, but
then iichid_attach() sets it back off, just before returning.
