The current 2.6 kernel is pretty good on it's own. If you're looking to patch 
it further though, there are only really two patches you need:
1) Ingo's realtime-preempt patchset 

2) the current realtime-lsm patch. it can be found in the broken out patches 
from the mm patchset

I'm currently using a kernel with the Gentoo patchset applied (for added 
stability and bug fixes), with these two added on top (for lower latency and 
the LSM capability). Works fine.
