Hi again.
Here is a draft patch for adding TuxOnIce support to the pm/defaults and
pm/functions files. I'm calling it a draft because I want your feedback
on whether it's the right sort of approach. I'm not really keen on
adding a variable per sysfs entry, and so have only added the most
frequently used ones in this iteration.
Victor, I'm not ignoring your comment about hybrid support. I'd just
already written the lines when your email came, and thought it might
never-the-less help to have on record how to do hybrid with TuxOnIce.
(This is only an RFC anyway).
Regards,
Nigel
