SD-Card MOD for WRT54G V1.1 = CDF3

On this side, I'll put down some information on how to do the SD-Card MOD on a WRT54G V1.1 = CDF3 router.

The router is working on WhiteRussian 0.9 and uses the module mmc.o v1.3.5 from Cyril which was modified by a friend of mine (Chris DD7AN) to use the right GPIOs.
Here is the binary of mmc.o.

• SD pin 5 = GPIO 3 = CLK (clock)
• SD pin 2 = GPIO 4 = DO (data out)
• SD pin 7 = GPIO 5 = DI (data in)
• SD pin 1 = GPIO 6 = CS (chip select)

Here is an overview of the board.
