Yes, idlemax is the answer. Type "idlepc idlemax /all 250" in the command line (bottom middle box) of GNS. You can change 250 to anything from 1-1500; you'll want a low number. Try 10 and if you can't console into your router just increase the value till you can. If you add another router just run the command again.
I have a duo core 2.1G Vista box running 30 routers at under 10% CPU thanks to idlemax.
