Hey Jarkko.

Since that is out anyway rather soonish, there's no need from my side
to get the fix into stable.

Right now I don't really have any... mostly because I had no clue on
how to further debug it (the only thing that I could think of would be
having a look at any serial console output, but the laptop has no true
serial port anymore, so best I could do would be to attach some
USB/RS232 adapter, and whether that even loads before the system does
something is questionable)

If you have any ideas on what I can do to give more information, don't
hesitate to tell.

But as I've said... it might just be a bug/missing implementation in
the firmware and nothing from the kernel side.
Cause it really seems as if the display and CPU fan don't even power up
after resume.

So,... I'm happy if you have ideas... but don't waste too much of your
time on this! :-)

btw: Fujitsu support wasn't really helpful on this matter, once they
read Linux they basically said not-interested.

Sure thanks :-)
