He does have the developer kernel correct

His boot log says he does...

I see this is a developer image!

So unless there is a bug with the player software identifying it that shouldn't be the problem. Perhaps the root partition is full and emphatic won't fit. If you can get to the shell you can use this command to check...

df -k /

or you can probably get your ftp client to tell you how much space is available (not sure how off the top of my head).
