I've enabled VIDI and FIMD and confirmed that they should up properly in
modetest before applying the series.
Booting with the atomic series works fine, but I get a segfault when
calling modetest. I've attached the kernel log below.

I tested the common usage scenario. In fact I can't really test with
FIMD anyway, since I don't have any panel that I can attach to the LCD
expansion port. Regardless of whether the kernel oopses or anything with
atomic, I can never make sure that the FIMD visuals are actually correct.
With best wishes,
