...with a stripped-down configuration but still with several
potentially performance-impacting debug options, i.e. certainly not
optimized compared to average distributor kernels.

I got no xruns in a day-long session with mplayer playing an internet
radio stream and timemachine recording to HDD.

Perhaps you can install a 2.6.38.y kernel alongside your f14 kernel, e.g.
from a package from here:
http://koji.fedoraproject.org/koji/packageinfo?packageID=8
(I don't have Fedora myself, hence don't know the easiest route.)

Having a current libraw1394 is a good idea too:
http://koji.fedoraproject.org/koji/packageinfo?packageID=628
Alas v2.0.7 didn't show up there yet.  (Users of the older
{ohci,ieeee,raw}1394 kernel drivers don't need to care about that;
libraw1394 v1.3.0 or later is OK for them.)
