Same as before.

No, I can't think of any 8.0 changes that would influence how you set
FSM size. There's been some speculation that with the new ARC code,
it might be worth increasing shared_buffers to larger values than were
useful before. I haven't seen any experiments to back that up though.
There are also some brand-new GUC variables that you can twiddle to
influence the background writer's behavior; and the existence of the
bgwriter might affect your thinking about how often checkpoints need
to occur.
pgsql-performance would probably be the most appropriate venue if you
want to discuss this more.
