Not really you can't... (or at least I don't think... I may be lacking a clue
on this though)

3550 IOS can't see stuff very well when they are going thru the ASIC (cef
in 3550 uses ASIC and hardware forwarding (which is why 3550 moves L3
packets really fast)).

Try exhausting your TCAM though by filling it up with 50,000 random routes
with default SDM :) You might start seeing something in debug ip packet after
that heheh (warning: don't try this at home err production)
