Hi folks,

It seems I'm a little out of luck :/

I downloaded the correct version kernel source, and it appears to not
contain the cp210x module at all:

How do I proceed? Can i take the module source from a newer kernel and
build it with this one? Or will I have to just use a newer kernel tree
altogether and replace the kernel they ship?

On a positive note, I do seem to have built the other modules correctly
(vermagic is same to the actual kernel modules now):

It misses a "GEODE" at the end though. What does that imply?

Actual kernel modules:
