You could put one on each bus, depending on the type of I/O controller you
have.

If you're looking for that many FE ports, you probably don't want a 7200
then, particularly if you expect to drive any of those ports at close to
wire-speed.

The theoretical maximum you could have would be
NPE-G1 w/ 3 10/100/GE ports
2 PA-2FE-TX, one on each bus
2 PA-FE-TX,

That doesn't allow for any other high-speed interfaces (DS3, E3, OC3, etc)
without exceeding the bandwidth points on the router.
