Actually, originally Cisco planned to release SUP32-XL or similar variant
with higher FIB TCAM space.  But they scrapped that plan near the end,
screwing many people in the process (I'm sure some cisco account reps got
earful about this from many people who bought sup32's in the past)-- I mean
hey, forcing customers to buy SUP720 plus may be new line cards (depending
on situation) is more revenue right?  This whole 220k+ ipv4 routing issue is
an excellent opportunity :)   

On the other hand, if you have the guts, try popping in a PFC3BXL card into
SUP32.  I wonder which IOS versions will actually recognize this and show ~1
mil. entry capacity when doing 'sh mls cef max' ;-) (WARNING: this
