Sorry for the slow reply. New laptop. Lets of setting up to do.

This looks like a good, simple and straightforward idea, and sort-of 
matches with Richard's "Can we reuse something in config.d?" question. 
It also makes things nice and simple if we add new entries (eg when I 
get around to finishing cluster support).

It does raise one question for me though - I'm dreaming of some day 
getting around to making a nice gui for configuring all these power 
management options (not just tuxonice). It probably wouldn't simplify 
that task much... perhaps we could think of a way to help there? ... in 
the hibernate script, we would have

procsetting compression/algorithm lzf
procsetting user_interface/program "/usr/sbin/tuxoniceui_fbsplash"

Perhaps something like that would be easy to implement and easiest to 
parse? (Yeah, it's sysfs now - procsetting is just historical).
