How to change the current song from the headset in the N900

Like some people i got a N900 during the Meego Conference, so far I’m liking it and already have a few ideas of development things for it. On the other side I’m trying to force me to use it as my regular phone so i can show others the greatness of a real Linux stack based phone, the main problem I’ve found is that my Nokia-Symbian phone headset has very useful next/previous/pause/play song buttons that do not seem to work on the N900. Does anyone know how to get this to work?

Meego Conference goers advice

I won't be attending the Meego Conference but i've been living in Dublin for 11 months so there is one advice i can give you.

Make sure you come with the correct clothes.
The weather forecast for the coming days is:
* Temperatures between 0 and 10ºC
* Heavy wind
* Rain
So bring a good coat (if possible water proof-ish and with hood), a scarf or similar and a hat/cap/something for your head.

I hope the Aviva Stadium was really cheap otherwise i don't understand why someone would like to have a conference here at this time of the year :D

Update: Remember that Ireland uses a different power socket than mainland Europe
