Is that a Sup-2T with PFC4XL?  Everything I'd read about it said it had 
the same FIB as the PFC3XL.  i.e.

http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps708/white_paper_c11-676346.html

The FIB in the PFC4 contains 256 K entries, while the FIB in the PFC4XL 
contains 1 million entries. These are the same as their PFC3x forwarding 
engine counterparts. The FIB in the PFC4 contains prefix entries for IPv4 
and IPv6 global address, IPv4 and IPv6 multicast addresses and MPLS label 
entries. There is a level of partitioning that exists to ensure there is 
always some space available for different types of forwarding entries. 
There is some flexibility from a user configuration standpoint that allows 
these partition boundaries to be changed to accommodate more of one type 
of forwarding entry. For example, in the PFC4XL, the default setting 
provides for 512 K IPv4 entries, and this can be increased through 
configuration control to support up to 1 M entries if required.
