CNN HD has been testing for a while now, there is some limited Freesat data there, so I'm hopeful it will join Freesat.
If not, if can be tuned in manually in non Freesat mode.
Tuning details are:
11.112 H, 22.000, 5/6, DVB-S, QPSK.
If you tune it in whilst it's still testing, it's under the label 50290 as opposed to CNN HD
