Hmmm, I don't think you have many other options. In fact, I just tried
it, and on my system it's a symlink as well. However, I know for sure
that they *did* work independently earlier, because at some point in the
7.04-7.10 area the second core got stuck at 2GHz after resuming from
suspend. For the record:

AFAIK it's the kernel, and nothing but the kernel. So this must be a
kernel problem.
