We are running 12.2.25S on a few 7206VXR/400 with 512MB RAM and it runs well
with MPLS VPN, BGP 2 Full tables, etc.  I have not tried it on a 300 with
256MB yet with those features active (but it should be ok as we have 290mb
free currently on the 400).  1 major thing we did notice was that MPLS
Ethernet interfaces on routers and switches needed the jumbo frame support
or traffic came to a crawl.  We didn't seem to need that with 12.0S.
