Well, as of right now it is just a tarball, and you will need to be booting from MMC with 1.5GB boot partition prior to untarring KDE. Its about 950MB to install.

Once I get my n810, I will release the final tarball, then I will see what I can do about an alternate install process. Well, we'll see what I can come up with? Its gonna be a month before Im gonna get to looking at that.
