Latest uBoot for Pogoplug Mobile? (no replies)

I just picked up 4 Pogoplug Mobiles from Ebay for a little less than $6 each shipped.

What's the latest and greatest uBoot for the Pogoplug Mobile?

Would it be davygravy's posted here - http://forum.doozan.com/read.php?3,7477? Is there a nice simple script to install the uBoot with the appropriate env variables? If not, why not? Just curious since a script makes it so much simpler and less error prone.

Thanks
