Thank you all for the help.
Here's my results with FA-101.
kernel: 2.6.14-gentoo #2 PREEMPT
libraw1394: 1.2.0
libiec61883: 1.0.0
libavc1394: SVN
freebob: SVN
jackd: 0.100.0 from freebob.sf.net
jackd -R -d iec61883 -o osc.udp://localhost:31000 -p 64 -b 64 -s 0 -i 8
-t 16 -r 8192
Rare xruns, mostly on client connection/disconnection
Interesting observation:
Output from jdelay initially shows 1298.7 (samples of input->output delay).
That is with 2 buffers of 64 samples!
My Delta66 gives 188 samples of delay with this setup.
With some xruns the delay increases:

P.S. After killing jackd and/or freebob, I can restart them without
device reset. No problems here.
