alas that's not the way this works.

I'd really love to see this thing working...

Well, recent "investigations" revealed that N9(50) harmattan *has* support for those multibutton wired headsets. So we might be able to backport parts of the driver stack to fremantle and integrate it into powerkernel. I've not yet looked into any harmattan sources for that, just studied the N9 schematics a bit so I learnt that the twl4030 companion chip there directly connects to the relevant pins of the AV-plug. Studying the datasheet of twl4030 was next to learn how all this works and how to adapt it for N900 where the hw is different, as for sure we won't get any support from Nokia for it.
Bounty usually doesn't help much, but donations sometimes improve the interest of devels to look into it ;-D

cheers
