Since I do not know what that is, then I would say the answer is no ;)
This is a very slimmed down ARM system, with a simple init.d script that
brings up the networking.
The other devices/buses are probed through the flattened device tree.
What probably is needed is a networking script that either waits for the
eth0 to become available or it must be started later.
But I am not too sure starting it later will help though.
