Related work

Can compile the kernel using Pazos kernel source using his shell script and bind pmOS generated initramfs with the kernel build with GCC 4.7.

The output to UART using MicroUSB cable with 520Kohm, 619Kohm and 150Kohm between ID and GND pins works, with the kernel config according to Command Line and serial output.
