I read the recap of the 2011 changes in the IAEI magazine and they are doing away with the whole "feeder" language in 310.15(B)(6) so you are going to have more surprises when it comes to feeders, even if they do carry the whole house load. Basically that table will only apply to service conductors if I read the change right.
Couple this with the 338 change and you are running 4/0 Al SER for a 150a disco outside to a 150A L&A panel inside.
If you have a 200a you won't be able to use SER at all
