I guess I can reply myself. The "No" answer probably refers to the
kernel resuming itself just with the help of the command line
parameters. Of course that is not possible. I did not even think about
that possibility, because I have used LUKS encrypted disks longer than
hibernate/resume...
What I meant is
echo -n "$major:$minor" > /sys/power/resume
I guess that should work just fine with LVM, shouldn't it.
I'll send a patch to clarify the answer in the FAQ.
Regards,
Uwe Geuder
