I do not think it is possible to access a computer which is in hibernation
state?
I use pm-hibernate, not pm-suspend, so the computer is really shutdown.
More interesting is the fact that when I connect to that computer, I more
often use the wi-fi itself ;) I do not have enough ethernet cables at home
so...
For the module thing, the only information I have found in the man is the
name of the variable (which you gave me anyway), nothing about file syntax
(and, of course, no sample is present) so I think I'll dig when I'll be at
home. I'll need some time to have my brain upgrade correctly :)
Sometimes I do not like man pages...
