The wiki page now contains instructions on how to connect the naviboard v3
to a graphics card [1]. This should enable everyone to use it and requires
only three parts: a VGA connector (or DVI or HDMI), a 3V regulator (LDO)
and a naviboard. Connect everything as described, plug it in, load the
i2c-dev module and run i2cdetect to check if it's working.
If the instructions are not detailed enough, please complain and I will
try to clarify any issues.

I tested this setup with the integrated Intel graphics card on my notebook
and it worked fine, a test with an nvidia card will follow. To find the
right I2C bus on your machine, load the i2c-dev module and run i2cdetect on
all available busses (look in /sys/bus/i2c/devices for i2c-*, or simply try
this: "for i in `seq 1 20`; do echo $i; i2cdetect -y $i; done;"). The
commands output should be different if your monitor is disconnected (or
switched off).

Have fun!
