. However, glancing through the SSE5 specification, I
can't see at all how such a dramatic speedup might be achieved. Does
anyone know any more, or can anyone see more than I can in the spec?

application-wide? What are the (security-related) implications in each
case?
They can safely be chosen application-wide, so long as they are secure
choices as per the Group parameter agreement section of the SRP spec.

that they use AES but I can't see where they tell us what mode of
operation they are using.

From the title it sounds like you're talking about my 2007 proposal:

This uses key stretching to increase the work of generating a colliding
identifier from 2^64
At a stretch, one can imagine circumstances in which trying multiple seeds
to choose a curve would lead to an attack that we would not easily
replicate. I don't suggest that this is really what happened; I'm just
trying to work out whether it's possible.
Suppose you can easily break an elliptic
