Does anyone know whether the 6500/7600 supports BGP-SD? That is one way
to have the full table in RAM but limit how much of that table is
downloaded into FIB.

For any routes that are not in FIB, you can have 0/0 or ::/0 to handle
that traffic.

This way, if you have any downstream customers that need a full table
from your 6500, you can still send it to them even if your FIB is not
holding the full table.
