Just have to pipe up and say three cheers for realtime-lsm. It was a 
very quick setup on my Gentoo Shuttle PC last night, and the got the 
latency of my PCI HDSP on that box down from a hideous 4096 frames per 
period to a wonderful 512 with "almost zero" Xruns. Huzzah! Alongside 
latest 2.6.10 "love-sources" [mostly MM patches], it's highly recommended.

I'm initiating it at startup with a "modprobe realtime any=1". This 
means that any user can get realtime priviledge, which is safe enough on 
a box off the net. But how risky do you think it is when there's an 
internet connection involved? For example, on a box left alone, hooked 
up to the web as part of an installation somewhere? You'd probably want 
to specify a Group or User ID of PD + Jack in that case, right?
