Yes, I want to chime in a bit here... the key phrase in the roadmap is "if possible". The plan is to definitely upgrade to a 2.6 kernel, and definitely add firmware support for larger battery sizes. But whether we can actually implement any kind of sleep or hibernate mode is very uncertain at this point.
Once we get a bit closer to that milestone we'll start looking into it and see what we can see. In the meantime, take it with a large grain of salt! But thanks for your enthusiasm and support! If you have any ideas for other iLiad improvements (or if you find any bugs) feel free to
add a new ticket to the project! (You'll need to
register first, but that's easy.)
