We don't have drivers like they do on Windows or Linux, b/c of the way IOKit 
operates. You don't need I/O drivers to support a device.

As I said you may need a more recent kernel build, machine profiles, kexts, ... 
It's not going to be solely an issue of "drivers".

I could speculate. You had kexts clobber each other, the hw was only partially 
supported by the overlays, basically since there should have been no 
expectation for that to work you were lucky to see whatever artifacts.

You're woolly thinking, not mine. You aren't accounting for how the OS operates 
from the kernel up properly.
