Actually, eq presets are stored on hda2, but most of the other settings (volume, etc) are stored in /dev/empeg_state, which is an autosaved area of ram (128 bytes).

We won't be documenting that area, as it changes regularly - we're on version 7 of the layout already :)

Can you spare a few bytes and document them as "reserved for third-party applications"?
