i think (and could be badly mistaken) that the results of your research 
might be a bit outdated.
on the one hand there have been huge improvements to lower latency in 
the kernel with recent releases, and at the same time there have been 
improvements on how to make realtime capabilities accessible by the 
ordinary (non-root) user.

personally i don't think you need any more voodoo on recent systems.
if you are still running a debian woody on 2.4.18, you might experience 
benefits though (some users are extremely conservative when it comes to 
os upgrading; how many of you w32 people are still running W98?)
