What kernel module if I may ask?

What machine is it?

abrasive?

No, I never had this machine. If I had a few, I won't mind doing in-depth
analysis of the hardware though (but if there's anyone else who would like to do
this, I'd pass on it ;-) ).

Did you compile the mainline linux kernel for correct machine ? Don't forget
this is ARM, the platform setup is pretty much fixed. That's mostly why you pass
machine ID.

Well u-boot should have serial console working. Later, you can enable early
console debug support (somewhere under kernel debuging).
