The problem here is that there is no available documentation for the
important parts of the Ipod. This means that the developers are to a
large degree in the blind about how to operate the chips. The result is
that some parts of the Ipod are most likely in an "awake" state,
consuming power, when they really should be turned off and the
developers practically no idea how to turn them off. Finding out these
details by reverse-engineering the Apple firmware is a hard and very
time-consuming job and not something a lot of the developers are very
keen on doing.
So you can really only blame Apple and PortalPlayer for using and
producing chips with no documentation.
