The camera does work when flashed to w880i but only in 2MP and W880i is actually walkman 2.

And these requesting your requesting isn't like your the first person to wanting to do this, since the K800i was released lots of people have wanted to flash their phone into a walkman version and have wanted all the features to work. Anyways the patch'es you are requesting does not exist and I don't think they'll ever exist to fix the joy stick problem.
