I did install the deb you posted on my 810 and a2dp playback seems a bit better. I can play to my headset using Kagu but still get a few skips/pauses in playback. Still also get skips when just playing through xterm/mplayer. But, seems better than the maemo 24 build.

Question for you RM. Why is your build twice the size of the Maemo build (5.x mb vs 2.x mb)? Is you build compiled in debug mode? If so perhaps a prod build may yield slightly better performance.
Thanks.
