I'm not sure I understand your question, but if there is something in
the /sys/kernel/debug/tracing/trace file that looks interesting you can
always get it out by e g "cat trace > /tmp/trace.txt", then "chmod 666
/tmp/trace.txt" or something like that [1]. Or is your problem that the
/sys/kernel/debug/tracing/trace file is empty?
I'm testing the 2.6.38-7 -generic, and it is in fact working better than
before. Almost as well as -lowlatency.
Only almost?
Anyway, that's kind of why I've losing faith in lowlatency personally -
I have yet to see someone showing me that it actually performs better
than the generic kernel.

[1] I bet there are shell veterans who know how to do that more elegant :-)
