I do not really see how to use command-line before the moment I have wrote
#pm-hibernate and the moment where my computer reboot?
Except the physical switch, I have no way to control the wifi between
those moments.
I am looking for the suspend_modules options, but I am not really
comfortable with modules... they are a part of linux I did not had enough
time to dig, actually (as for all kernel stuff, video configuration, and
sysVinit scripts, I have some fear to go too deep)
