Indeed, roxfan already wrote the first firmware dumper (attached) which extracts the content from data.bin. The two resulting tar-gzipped files contain a kernel image and a cramfs image:

Librie firmware dumper 0.1
Expected versions: 1.0.00.04081 - 1.0.00.04201
Device name: EBR1000

Decoding version...done.
Decoding os1.tgz...done.
Decoding os1.tgz.csm...done.
Decoding os2.tgz...done.
Decoding os2.tgz.csm...done.
Decoding mstick.tar...done.


The CramFS image is mountable on linux with:

>mkdir /mnt/wfb
>mount -t cramfs -o loop cramfs.img /mnt/wfb

You need the cramfs file system kernel module enabled to do that.
