10.04 does have a real-time kernel in the repos, 2.6.31-rt. But the 
2.6.33 real-time kernel from Tango Studio is superior. At least, I 
didn't have a lot of success with the real-time kernel from the Ubuntu 
repos while the one from Tango Studios is still going strong.
Later versions of Ubuntu do not have a real-time kernel available 
anymore, only via PPA's. But indeed, with the whole IRQ threading thing 
being merged in the mainline kernel you could ask yourself, do I really 
need a real-time kernel. In my case I dare to say yes, haven't done any 
A-B testing with a low-latency kernel but I get the feeling that I can 
get the most out of a real-time kernel. That's why I'm thinking about 
switching to Arch but unfortunately the 3.0 real-time kernel is not 
stable enough (it crashes on any plug-in that uses the Juce framework, 
need to file a bugreport).

Best,
