Hum, I run a couple of them for IX stuff...

With a sdm prefer routing, you can handle :

sh sdm prefer
  The current template is the routing template.
  The selected template optimizes the resources in
  the switch to support this level of features for
  8 routed interfaces and 1K VLANs.

  number of unicast mac addresses:   5K
  number of igmp groups:             1K
  number of qos aces:                512
  number of security aces:           512
  number of unicast routes:          16K
  number of multicast routes:        1K

Anyway this is really low limits.... But can help sometime.

Another stuff, there is some limitation ... ie ip prefix-list that  
handled by configuration of the switch but not evaluated when bgp is  
running :/
