I tried to use this image, but it doesn't work for me. I think I am missing something.
I had two tries with the same result -> It stops booting after recognizing my USB device (keyboard).
The only difference was that I the first try was using the special cylinder/.. partitions as recommended here http://wiki.gentoo.org/wiki/Raspberry_Pi
. In the 2nd try I preinstalled Raspbian and formated the partitions afterwards.
On my laptop with cardreader I mounted partition 2 and copied the tar.gz to it. Than I just used
tar xvfpz raspberry.tar.gz
Then I mounted the fat partition to boot and copied the files from boot2 in it. Unmount all and tried to boot.
