Using 'copy-nand', flashed ~cjb/rawhide-xo 20090528.img to XO nand.
My experience with rawhide-xo 20090528 matches that with 20090525.
One significant fix that first showed up in 20090525 is that the
OLPC keyboard (e.g., the Frame key) is now being recognized.
One problem that showed up in 20090525 is that Sugar does not pick
up on the 'Desktop' font size specification set within Gnome. The
result is that labels (e.g., in My Settings) are now really tiny.
A bigger problem, which I first noticed with 20090525, is that
Neighborhood View is empty (except for the 'me' icon in the middle).
[In contrast, my rawhide-xo 20090519 system's Neighborhood View
shows both existing wireless access points and existing wired XOs.]
