Will try to prepare that tomorrow.
Target kernel config must be cleaned up, it's redundant in some places 
and overrides some things which it should not.
I've managed to get usb working, it was kernel config error again (and 
Hans' patch he sent earlier is actually working). But still usb has 
problems, e.g. I couldn't get both ports working, only one of them.
SATA seems to be working out of the box, which is good!
