Can all 52 ports be active just not pumping 1gig of data?  Or can you only
have 48 port in 'no shut' mode?

It is about time Cisco did this.  What would be really cool is if they made
a 1 RU chassis that supported a 6500 series blade.  That way we could start
with 1RU in small datacenter deployments then upgrade to a
6509 chassis and use the same card.
