That's correct.  The interposition spec
<http://www.openbios.org/data/docs/rec.intpos.d02.pdf> says that
interpose should be "invisible" to interpose-unaware (e.g., IEEE1275
or existing) clients.  The SunOS boot loader doesn't know about
interpose, and so expects ihandle>phandle to return the phandle to sd.

It looks like the specified way to query for interposed packages is
via "instance-to-interposed-path", whereas the previously specified
"instance-to-path" omits any reference to interposed packages for
backwards compatibility.
