Do you mean to say in the first sentence "...that _do_ need to implement..."? If not, then extended sounds like a misnomer and the two sentences seem to contradict one another.

Yeah, but right now, it seems to me to be a bogus limitation for drivers to have no way of automatically loading firmware when you're about to hibernate. (Of course I've since been reminded of the notifier chain - that should probably be mentioned here as the way of achieving this). By the way, I'm going to go on record now as saying I think dropping the freezer is a silly idea. I'm therefore currently considering including the freezer in TuxOnice from the time it gets dropped from mainline. I know that will only make it less likely that TuxOnIce gets merged, but I've given up caring about that anyway - caring about merging is pointless when the people who decide if it gets merged don't care.
