Not a solution for the short-term, but it will probably get easier in
the not-too-far future.

A few weeks ago I created proof-of-concept: a small daemon that switches
to "performance" when starting an audio session and return to power-save
mode when done:

http://rg42.org/oss/jackfreqd/

Paul Davis and Torben Hohn suggested to integrate that feature directly
into jackd. See discussion on the Jack-devel list "jack frequency
scaling daemon" December 14/15 2010.
