The mailinglist is closed already cause of a possible lawsuit. Let me
quote Bob Ham:

> The GNU lawyers have apparently stated that this PowerVR reverse
> engineering project should not be hosted by the GNU project (on
> savannah.nongnu.org) as there is a risk of the GNU project being the
> subject of a lawsuit. Yay for lawyers!

> Unfortunately, that means this mailing list is now closing. I
> apologise for the inconvenience.
