We do that as well (but different environment). We have a 5500 with
NFFC-II cards for layer-3 "switching" and feed a 7505 over 2FEIP cards
by fast etherchannel ISL trunks. Routes IP/IPX between over a dozen
VLANs without blinking. A 4500M with FEIP can do quite a few as well,
but doesn't support portchannel.
