12.0(27)S5 has been absolutely bulletproof for us with exactly that port 
configuration.  We got the hint that we should be heading towards 
12.0(32), so we went to 32S10 on some "core" nodes (FE, DS3), but don't 
see any particular improvements there.  VIP4-50s would help you 
tremendously, but I know what it's like to have to use what you have.
