This looks like 2.1.1 but with a newer kernel (ie, all the menu, movie/music player files etc are identical to 2.1.1). So if you're upgrading from 2.1.1 you can just install gp2xkernel.img and ignore the rest. If you're upgrading from 2.0.0 you should install everything. No idea what the kernel changes might be though.
