The IN-ADDR.ARPA delegations for RFC1918 space are just like any
other block. You'll just end up hitting IANA's blackhole servers,
and not all that much, the cache times are one week.
Also, those blackhole servers are anycast, so they might even be answered relatively locally. See <http://www.as112.net/>.

Of course, the obvious "fix" is to run your own internal DNS which
is authorative for your RFC1918 addresses.
