Even then it will work, sort of.  Just configure the peer as AS23456.

You'll lose AS-path filtering capability, though, and if you have multiple 
32bit peer ASNs, it will be hard to figure out who is who.

If you have a 32bit ASN yourself, then you're doomed.  (You could buy
a Vendor J router, they have implemented it on time... - it's not like
"it's especially hard", or "cisco has not been told that the ASN clock 
is ticking" or even "Cisco folks have taken part in writing the relevant 
32-bit RFC").
