A side note is that F6K DFCs are not supported on SXI and are end of life. http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps708/prod_end-of-life_notice0900aecd806d9953.html They may work but they are not supported.
The 6548 cards are also End of life (meaning you can get them cheap but can't get support) http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps708/prod_end-of-life_notice0900aecd8069af87.html If you are upgrading and have money to spare you may want to look at the 6748 cards.

It is a bus-based sup, no xbar fabric whatsoever. >Even if the line cards have the DFCs, can the SUP32-3B take advantage of them? DFC + sup32 = not supported/possible. Basically you're trading one bus-attached 48 port 1G card for another. There are some benefits perhaps - qos capabilities, possibility to u/g to sup720 in future & get fabric connections & add DFCs for more performance - but for now, they are pretty equivalent.
