We're trying to use the standard kernel/driver interfaces when possible,
but for things that may have a good deal of variation in implementation,
we're looking to provide a very thin "hardware interface library" layer
to adapt between the bottom of the userspace stack and the drivers or
whatnot for specific hardware platforms.  

We'll continue to adopt standardized kernel solutions as they become
available -- We're now using the power supply framework in 2.6.24 for
monitoring battery/charge state (post M5 SDK -- it'll be in the next 
release), for example.
