I've managed to resurrect my OLPC and got a developer key as well. Now all I 
need is some time to install the rawhide-xo image.

Hopefully I can test it in 1-2 weeks.

Note that I received a mail from a Saeed Bishara who noticed a bug in the 
cafe driver that should be fixed by this patch:

--- cafe_ccic.c.orig	2009-05-02 17:57:08.000000000 +0200
+++ cafe_ccic.c	2009-05-02 17:57:37.000000000 +0200

 	chip.match.addr = cam->sensor->addr;
 	ret = __cafe_cam_cmd(cam, VIDIOC_DBG_G_CHIP_IDENT, &chip);

I think this will resolve this issue.
