Yeah, it compiles and boots. I just wasn't able to conclude that the
patches where working properly.
But, I found another email from Sibi regarding the starvation reported,
it turns out that this version of the modem firmware requires diag to be
present. So after launching diag-router the modem is up and running.
As such, I've merged the series. Let's try to figure out the clock
situation to make it functional out of the box.
