!! Discussion

Just started looking at this device. It's interesting for a number of reasons: 
* Has MINI-PCI using an open source driver
* Has USB interface

!!! Firmware hacking
Kernel starts at 0x00000000 and a JFFS2 Filesystem at 0x00140000

JFFS2 starts with magic 0x1895

extract the filesystem:
    dd if=wgt634u_1_4_1_9.img bs=1 > rootfs.jffs2

mount it:
To mount a jffs2 filesystem you need to use the mtdram device. You may also need to creat the device to mount ( mknod /dev/mtdblock0 b 31 0 )

    
    modprobe mtdcore
    modprobe mtdpart
    modprobe mtdram totalsize=32768 erasesize=256
    modprobe jffs2
    dd if=rootfs2 of=/dev/mtdblock0
    mount -t jffs2 /dev/mtdblock0 ./mnt

Inside is a bunch of lrp packages. On boot the device creates a ramfs then unpacks the .lrp packages into it. A .lrp is a simple package inside a tar.gz archive.
