I worked a bit on Wesnoth for N8x0. I did a test compile with some of the changes Glenn Ditchfield (the original maemo Wesnoth maintainer) did, and got it to run in scratchbox, so it is definitely doable.

There are some issues with fremantle and SDL programs (such as not being able to use the top left corner) that may have been resolved with the PR1.1 firmware. I will do another test compile and check.

I can't promise fully polished packages, but I will see what I can do as a stop-gap measure. I want to play Wesnoth on the N900 too!
