It depends where your kernel comes from. If you're using a stock Linux kernel compiled yourself, then yes you probably need at least 3.9 for it to work. Sometimes if you're using a vendor supplied kernel they backport support for features, so it is not always clear what support there is in a kernel. Linux 3.9 and Linux 3.10 have very different amd15h northbridge support. If you're looking for long-term usability of your project/tool/research you probably want to jump straight to 3.10 so you don't have to make everything work on 3.9 and then change it all again when you move to newer kernels.
