IMHO this is a bit ironic. Generally, if there is a complex problem that
can be divided in smaller parts, which are possible to address one at a
time, this should be the preferred way! Divide and conquer, my friend : )

Applied to the suspend dilemma: once we get suspend2ram working
perfectly, the only thing we still have to care for is saving the memory
image someplace, right before telling the hardware to sleep or switch
off. You might get the benefit of chosing between power-off for ultimate
power savings vs. speedy suspend2ram, yet with a backup on disk in case
something weird happens to the power supply. Nice, huh?

I've been a happy suspend2 user for quite some time now, and I have to
admit I don't much care how broken the design is - for now it works, the
only alternative is just as broken, and did not work as well last time I
checked. And heck, I just don't have time to check with every new kernel
I build. Talk about working setup vs. academic progress, which in turn
will lead to a clean working setup maybe some time soon, may be later,
but not now. I'll look into it as soon as any progress is visible and
time available), s2ram is nice even on a laptop without battery ; )

Kind regards, and welcome to suspend2 family!
