Suspend-to-disk is only one part of that suspend package. It also
supports suspend-to-ram (which I guess you knew).
As for Linus' opinions, I don't care that much. In my opinion he has
some interesting views but he is too much of a know-it-all. I think
that when no proper solutions exists, workarounds are perfectly
acceptable. I know what I would choose between using a workaround and
writing a kernel patch that fixes resume on macbook.
