I experienced too,  that the needed settings are not being done, if one
only installs the lowlatency-kernel in Feisty. Word is given, that it is
 done if one installst the metapackage or the Ubuntustudio-Disk itself.

In my case, I needed to hack /etc/security/limits.conf and do some more
of the stuff decribed here:

https://help.ubuntu.com/community/UbuntuStudioPreparation

afterwards, it all works fine for me (1-2 xruns/h under serious load
with settings like this:

/usr/bin/jackd -R -dalsa -r44100 -p128

looks like the lowlat-kernel is not running or limits.conf is not hacked....

good luck:-)
