We did something similar - after upgrading the MSFC2 on one box from 256
to 512 MB, we used the 256 MB SODIMM to upgrade the Sup2 on another box
from 128 MB to 256 MB. Worked like a charm.

You really want 256 MB on the Sup2. This is the memory consumption on a
6509 running native IOS with 256 MB on the Sup2 and 512 MB on the MSFC2,
