I missed this discussion mostly, but here are my thoughts.

Why not provide also a HAL based kpowersave just for R14, alongside with 
the new improved one that Tim wrote? This is a phasing out period. After 
R15, we drop it entirely. That gives everyone a heck of a lot of time to 
work out their issues.

I like the release mantra "make each release suck less" and that's what 
I think our goal needs to be. We can't ship a perfect release, but we 
can improve from every prior release. it may not seem like it, but many 
a bug has been sqaushed since November 1st. I don't have a great gauge 
on this, but 187 bugs have been modified, and are resolved since 3.5.13. 
barring any bugs that were modified, reopened or anything else, 187ish 
bugs have been resolved. I think this is tremendous progress. 29 bug 
reports sit with "Patch Avail" which I think should be all considered 
release blocking in a sense. We have those patches available, we should 
get them out in the wild by the next release.

Just some thoughts,

Calvin

PS. why not just call it TPowerManager? It's not really for "saving" 
like kpowersave, because my intent could well be to run my system at a 
maximum rate, what it's job is to manage the power related aspects of 
the system.
