Well I guess that should be it, I am using an initrd so... what are my opti=
ons?
If a patch my kernel sources with swsusp2 will it work? I assume it
will from your statement above. I'm guessing, thats the way to go
then?.
On another matter, is there any place to put scripts to be executed
upon resume? This is to "reset" things that dont come up nicely, such
as alsa and the like.

Thanks a lot=20
