(This is port-mac68k specific, so others can ignore...)

In working at getting the MacOS ROM-based slot manager code to work under
NetBSD/Mac68k, I've run into a bit of a stumbling block:

During initial device attachment, the ite minimal console code inherits
some values from the grf device to which the ite is attached.  Later on,
using some new IOCTLs, the display can change "modes" requiring that new
values be "stuffed" into the ite device.  (In particular, things like
frame buffer address and geometry are the main concern.)

So, given a pointer to the grf_softc for a particular grf, how can I
determine, in a supported way, if there is an ite attached to that grf?
Keeping in mind, of course, that an ite might be attached to any of
several grfs...
