As I mentioned in some previous mail, it is quite easy, just redefine O_DSP_H on line 44 of arch/arm/mach-omap2/board-n800-dvfs.c Here is testing kernel with this state defined as 400/133. http://fanoush.wz.cz/maemo/zImage-2.6.21.0-osso63-dsp133.tar.gz Tried few mp3 songs and radios and didn't hear any problems, 128kbps is absoulutely fine and I didn't notice any problem also with VBR with average rate ~160kbps (some frames even 224 or 320 kbps). I don't have any music in AAC or very high constant mp3 bitrate.
