If anyone really wants that few percent speedup on n770 and wants to flash custom kernel because of this, let me know and I'll provide a link for such kernel image if you cannot compile kernel yourself with that patch. Also if such adventurous soul has relatively new N770 device I would need a tester for tearsync (i.e. tearless playback) feature, see this

and bottom of this

you should have higher HW build version in /proc/component_version than me (1602) and are not afraid of flashing kernel. On my device (one of the first ones from November 2005) it simply hangs. It may be that on newer device (newer HW build) those pins inside are connected \and tearsync feature will magically work. But it may also be that my code is buggy and most probably the device will hang when enabling the tearsync feature with mplayer (default is disabled). Otherwise such kernel should work as usual but without any warranty of course :-)

Serge, is the tearsync option for -vo nokia770 in .17 too?
