I'm also having real good experience with Ubuntu 10.4 (slightly customized with the UStudio packages). I agree that only Firewire devices performance seems to really improve with a RT kernel.
In RT with a Ricoh chip and FFADO from svn I can have 8ms latency (I only tried using 6 channels and 8 i/o open), although I have to note that a few times with heavy load of audio streaming amongst different applications jack dies and needs to be restarted. I didn't need to set IRQ so far. In non-RT I use a edirol ua-25 which works pretty good with low latency too (but not as good as firewire rt).

Hi Pierre,
There is also the Puredyne repository avalaible with ubuntu (karmic or lucid) with their own set of packages for PD :
https://launchpad.net/~puredyne-team/+archive/ppa?field.series_filter=lucid
(you can just add it with : sudo apt-add-repository ppa:puredyne-team/ppa or with synaptic and take what you like)
I use the 64 bits on my desktop with the RT kernel (2.6.31-11-rt) with a jack setting that gives 4 ms (PS :Also with the debian tools you can build very easy your own RT kernel packages if you want to.)
