In the dmesg output you should see two ttyUSB devices enumerated when the FTDI is detected.  The first is the serial console.  I'm not sure about your setup but if you have a 4 port serial adapter I would expect those are ttyUSB0 - ttyUSB3.  This would make the FTDI ttyUSB4.

The first thing we need is that you can see the serial console.  In some ways I wish this was like the beaglebone where you would see CCCCC when no SD card is loaded to know your serial connection was working :(

Ethernet won't work until later kernels.  I haven't tried the one Denys just updated to yet but ethernet is supposed to work there.
