The charging of battery is entirely controlled in HW. I don't think the
actual power adapter has anything to do with it though. The ring color
is a trick but is, I think, controlled by the machine (or maybe is
related to the amount of power "sucked" by the laptop, dunno for sure).
There is a trick though, there are apparently several kind of power
adapters, some below 65W and some above or something like that. OS X has
some code to detect the wattage of the power adapter and eventually
force the machine to run low speed when charging a batter or something
around those lines when running on a "weak" adapter.
I don't do that in Linux.

I don't think it's a kernel problem. In fact, I don't think there is any
problem at all..
