Sleeping (i.e. S1) worked fine here some months ago, but i didn't try
recently. I'm fine with shutting down, it's fast enough for me...

Well, there is no use in doing Suspend-to-disk when you have a system
capable of doing this in a sane way as swsusp hopefully does ;)
Interrupting the OS and forcing it to hibernate via BIOS is kind of
broken by design IMHO...
And Suspend-to-RAM is kind of weird, too... As far as i can see, the
difference between sleep and StR is that devices are powered down
instead of put to sleep; so after waking up they need to be properly
reinitialized - i don't think many device drivers do that properly...
and it might need a lot of software support, too.
So it's the much more difficult than sleep (where i guess that Hardware
is supported to keep it's state by themselves)
