Here are some WIP news for mpc2x. There is no release yet:

mpc2x is a mpd client for the gp2x handheld console. A gp2x is a Linux based ARM powered multimedia platform, which because of it’s Linux OS is very well suited for writing your own applications. At the moment mpc2x is nowhere near any release state, and has only a functioning song display at the moment.

mpc2x is written with help of the SDL multimedia library which is as far as I know the best option on the gp2x because it would be rather an overkill to use and X server and some tk to create the interface.
