It looks like jackd detects your cpu as supporting 3DNow....

But then when it tries to use it it bombs... how could that be? Maybe
there are different levels of 3dnow and jack is not smart enough to know
that? (the use of the extra instructions is supposed to happen
dynamically at run time). 

Hmmm, you could try the Fedora Extras package while I try to find a
solution (the problem is I don't have something to test on that will

The Fedora package is not compiled to use sse/sse2/3dnow dynamically so
it would be less efficient when you have capable cpus, but maybe it will
work in your case till I find a solution that works on all cpus. 

Download the rpm and install it as a "downgrade":

(I think you'll need to do a "rpm -Uvh --oldpackage ..." to install it.
You will also need to either download the other two or erase the -devel
and -example-clients packages).
