Realtime-lsm is the most usefull patch in my situation. I don't like running 
stuff as root and RT-lsm allows me not to have to do that. It's use in 
creating best latency on it's own...well, it does not match what I had with 
the 2.4 kernel in Mandrake yet but it still enables me to record in Ardour, 
run jack at 512 x 2 as a user on my Delta1010LT with FX monitoring and is low 
enough latency that I can play a guitar through it live running Ardour and 
LADSPA fx like delays, reverbs and chorus'  without the unsuspecting knowing.  
The only issue I find is I have to let my MDK 10 box catch up after I start 
jack then ardour other wise Ardour drops the jack pipe. Other than that it's 
fine.
