Well, the appropriate backend for this is still missing on Maemo. Let's see what Instinctiv will come up with (which will be closed-source, though). Gapless playback does not go together with MAFW (so expect more stuttering), and may be more stressing on the battery as the DSP might not be usable for decoding gapless. But I'm no expert on this, so maybe it would work well even.
