OpenWrt on ASUSWL-520GC (admin, admin)

Notes:
   The firmware installed is the version: 2.0.1.1, the ip address
   is 192.168.1.1, the web gui can be used by admin, admin.
   After reflashing the board, the old firmware should be available
   in the cdrom shipped with the router.

OpenWRT compatility:
1. The 2.4 kernel version has some troubles accessing the flash
   and this will actually make the board hang after a while. 

2. The 2.6 kernel does not have the same issue, except for the
   open source b43 wireless driver, that make the board reboot
   as soon as it is loaded.

For this reason, when configuring the kernel option from the toolchain
menu, the wireless target profile to choose should be `No WiFi'
