Sounds great!

Soon these new GTA02 devices will be produced, they are scheduled for
April I believe.

Amen brother.  The quilt stuff (I call them "mokopatches") will soon be
deprecated in favour of all git.  But I already maintain a git tree for
a couple of months here:

http://git.openmoko.org/?p=kernel.git;a=shortlog;h=andy

Note that it is layered, so master is kernel.org 2.6.24, mokopatches
branch adds the quilt blobs, and the "andy" branch on top has my current
stuff.  That branch keeps getting emptied into mokopatches currently via
posting for review to this list, so there is a varying amount of stuff
there despite plenty has gone through it.

Wah also note we currently abuse the ID pin I believe for charger
detection (a resistor to 0V is present in the 1A-capable charger that
hooks to the mini USB port).  But I'm not sure I see that changing for
GTA02.

I will ask about it but in the worst case in can be April.

Very nice to see you are interested to work on this subsystem!
