+Get the latest image: http://www.raspberrypi.org/downloads (the recommended one)
+And write it on the SD Card:
+dd bs=4M if=~/2013-02-09-wheezy-raspbian.img of=/dev/mmcblk0
+
+Note: I had to unplug/replug the sd card in order to see the second partition.
+
+On a debian/ubuntu host:

+On a gentoo host:
