I don't think more RAM will change anything if you don't swap at all.
You can try to set shared_buffers lower (try 32768 and 16384) but I
don't think it will change anything in 8.1.
The only thing left IMHO is that 8.1 is choosing a bad plan which
consumes a lot of CPU for at least a query.
When you analyze your logs, did you see a particularly slow query? Can
you compare query log analysis from your old server and your new one?
