I hope I don't cut off too much by answering that it seems, you'll have to:

1) keep the system-wide font and request it to be updated if it's not up to 
you, so you can't remove either;

2) find out if TL2009 libertine is linked in with fontconfig (perhaps check 
/etc/fonts for a link to texmf-var/fonts/conf/texlive-fontconfig.conf, if it's 
done the same way there) -- if it is, you have to specify exact font path, I 

3) likewise don't link that fontconfig.conf for the local TL with fontconfig;

4) remove the local libertine...

As you'll see, I too just consider how to build my fonts setup and have more 
to ask, but you can give that idea a try...

Well, but it appears that XeTeX is strictly requiring a font to be available 
just in one location... It sure would be nice to have some way to tune it's 
behavior when it comes to choosing between multiple versions, so that it would 
not take any messing with *TeX sources... But can it / will it ever?

Apart from that, I've read that you can give an exact location of the font you 
desire, so you could be using whichever you need... With that kind of a 
problem -- having to specify and making sources less portable!
