The bad news is that this is not currently possible. The previous version of Opensync did work for me but I have not tried to build that old version of Opensync for the chinook (OS2008) release.

I have built the current development version of opensync for chinook but currently bluetooth sync does not work. I am working on understanding why not at the moment.

I'm not confident I will have it sorted in the next month! If you are interested in hearing about my progress I suggest watching the opensync-devel mailing list, where I am asking questions!
