Hopefully I can do some of that.

Fair enough!

Ahh!  As the light dawns, it sounds kinda like something from a Dr.
Seuss book -- I said what I meant but I didn't mean what I said.  As
far as step 2) in the sequence, I was talking about the srpms from
Matthias' repository which I think are ready-to-build <insert favorite
distro here> sources with Suspend2 patches and the appropriately
modified rpm spec file all in one package.  What I should be working
with (reading between the lines of your response) is the Suspend2
sources, which, I guess, I should be downloading from the
Suspend2/TuxOnIce website.  Is that correct?
