I forgot to mention the software build we are using and also I am not
sure how to find that out. Reading /etc/fedora-release I just get:

OLPC release 11 (Leonidas)

Kernel version is:

Linux localhost.localdomain 2.6.30_xo1.5-20090908.1416.1.olpc.d1b0c02 #1
PREEMPT Tue Sep 8 14:24:21 EDT 2009 i686 i686 i386 GNU/Linux

And partition layout is:

[olpc at localhost ~]$ mount
/dev/mmcblk0p2 on / type ext4 (rw,noatime)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
/tmp on /tmp type tmpfs (rw)
varcacheyum on /var/cache/yum type tmpfs (rw,mode=755)
vartmp on /var/tmp type tmpfs (rw)
none on /ofw type promfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
gvfs-fuse-daemon on /home/olpc/.gvfs type fuse.gvfs-fuse-daemon
/dev/mmcblk0p1 on /media/Boot type ext2 (rw,nosuid,nodev,uhelper=devkit)
