this blog (source of this picture too) for those who read Norwegian.
The inscription isn't very clear from the pictures (and Arkeologi i nord has a lot of them), but it apparently starts out eknaudigastir ... "I Naudigastir ...'. It's silly to speculate about even the meaning of the name (though I'm sorely tempted and can't stop my brain from trying). I don't think the morpheme naudi- is attested in other early inscriptions, for instance, though it's very familiar from Old Norse.
Here's hoping we'll soon know more.
