Props go to Mike at IHaveAZune.com for putting these pieces together in an email conversation we were having.
Earlier the code for this infamous Zune bug showed up on Digg. This code is actually code written for Freescale’s MC13783 PMIC (PDF Whitepaper) and it seems like its affecting other players that have this PMIC like the Gigabeat S Series. This makes a lot of sense since the Zune 30 was heavily bases off of the Toshiba S series. So far it looks like the Gigabeat owners are trying the fix as the Zune 30 owners, letting it fully discharge. So far one user has been successful using this method and changing the date on his PC.
