Well, I had a look before posting this reply, and ran away from it.
I've gone back to it several times since, and got a similar reaction.

I seem to remember that it looked _more_ convertable when I looked at
it when doing the generic suspend/resume support - I could see a nice
simple way to pull out the saving and just leave the PLL resume stuff
in SRAM.

I'm now convinced that if I try to convert it use the generic support,
it will end up being a horrible broken mess.
