Yep, it's part number SUP720.  :-)  Seriously though, I'm not sure 
if they have a bug id for it.  I've always been under the impression
that this was an accepted, inherent limitation in the hardware for
this platform in having to process switch TTL=0/1 packets, but
perhaps someone else has additional details.
