[c-nsp] Cisco 4900M onboard X2 and twingig convertors

[James Edmondson]

They do not, i have 24 of them up in production, you have to use the half
cards.  I was unsure of this as well and had to work with my Cisco Rep to
verify this before buying them.  Documentation below must be updated it
shows Table 1, that the Twin Gig is only supported on the 8 port and 10
gig Ethernet half cards.
