Personally I'd do all my L2 Agg somewhere else....thats actually exactly 
what I do in most/all the places I have control over things.  Works lots 
better, way cheaper, unless you need weird interface types for some reason, 
in which case you probably should be re-thinking bridging anyway.  Routers 
are not good bridges.
