i vote for an X-Moto port

i used to have it on my old nokia 6680 a good few years ago and it was pretty much exactly the same as elastomania

infact if you check these links, youll even find the linux source code:
http://xmoto.tuxfamily.org/
http://ftp.debian.org/pool/main/x/xmoto/

now all we need is a kind experienced person to put it together for n900
