git://dev.laptop.org/olpc-2.6

They are working in the olpc-2.6.30 branch, currently.

I do have the hardware, and I've taken on the responsibility for making
pieces of it work.  In my mind, that includes being responsible for
mainlining things too.  I will start to work in that direction; 2.6.33
should be a reasonable target for the bulk of it.

My thinking, FWIW, is to turn the viafb code into something more like a
regular multi-function device driver.  I've already integrated Harald's i2c
stuff with the OLPC code; I need to add proper GPIO support next.  Then
there will be the V4L2 chunk for the video capture engine.  Along the way,
I may try to introduce some foreign concepts like locking.

I have a tree on git.lwn.net now, but it's against the 2.6.30 base.  I will
try to bring things forward to a more current tree sometime soon and put it
up as, at least, a place where we can see the various lines of development
going on.

Sound good?
