[c-nsp] 7500 slot configuration

[jp]

If the last vip is a spare, I'd keep it out too. If you lose a router 
due to a surge or loss-of-blue-smoke, the vip will be much safer in a 
static bag on a shelf.

I think, but am not certain, that the buses on each side of the RSPs are 
seperate. How data gets between the cybuses, I don't know, and it's a 
good question . It would be best to have the highest traffic devices on 
the same bus, (or in the same VIP if they will fit).
