Hi Martin,

It is also possible to use 64Studio's kernel (2.6.29-1-multimedia) in 
Ubuntu 8.04. It is complete preemption kernel. According to my 
experience, it is much better than the rt-kernel of Ubuntu Studio 8.04.

Below is a link to my very much unofficial tutorial for upgrading 
Ubuntu8.04/Mint5 to 64Studio 3.0beta. It's been working well here and 
for the few others who have tried it out. I wrote it because 64Studio 
3.0beta installer was not working with my laptop and this seemed to be 
the only way to get 3.0 up and running.

Please note that I have not tried this with Ubuntu Studio 8.04, I cannot 
guarantee anything. It might be better to try it on a clean install of 
regular Ubuntu 8.04 (or Mint5).
