How big a problem this is depends on what you need it for. I don't know too much about it but it looks like the real time kernel is useful if you need low latency audio. Do you need real time capabilities? I don't think you can downgrade the whole system to 8.04, if that's what you're asking. You can install 8.04 and upgrade later, though generally it's recommended to do a clean install. Also, if you enable the medibuntu repository for ubuntu, you'll have access to all the software Ubuntu Studio bundles, so there is no reason to install the Studio edition separately if you are already using ubuntu. http://www.medibuntu.org/

We were all new to Linux at one point. My one year anniversary of ditching Windows is coming up in January, so I'm not exactly a veteran yet. Mostly I google a lot and fake the jargon as best I can. I've tried dozens of distros at this point (except Slackware - I probably should give that a whirl), so I have at least passing familiarity with how a lot of them work.
