but that doesn't run. Does anyone know what the name of that audio output is on Maemo?

Code:

pactl list | grep monitor

says that sink.hw0.monitor is the right source (bluetooth devices seem to use sink.hw1.monitor).
And sink.music.monitor will get you exclusively the output of the built-in mediaplayer. However, remember to get rid of the pulsesink output, otherwise you'll just get a bunch of echoing as it tries to play back the output to the same device:

Code:

gst-launch pulsesrc device=sink.hw0.monitor ! audioconvert ! goom ! ffmpegcolorspace ! xvimagesink

should suffice.
