Sorry. I prepared the patches against the version of pm-utils I have installed on my desktop machine (Gutsy, slowly migrating to Hardy). I've received the email from Richard pointing to the git tree and will prepare patches against that. >> The other area I'd like to add support for is setting the various >> configuration options for TuxOnIce.

All of the options are configured by simply doing echo > /sys/power/tuxonice/whatever. A complete listing follows, with brief descriptions appended. The short answer is that the options allow you to enable/disable/tune features according to what's optimal for your computer, your usage preferences and/or for debugging. I can provide full descriptions for all of the options (I'm in the process of updating the Documentation/power/tuxonce* files, which contain descriptions of these options anyway, so that can do double duty).
