You mean to build Debian's 3.2.0-4 with my config ?  I could try that
I guess but it wouldn't tell us much because it might be that 3.14.34
needs different config options to work properly with this controller.

You're thinking the problem is initramfs plumbing ?  I'm sure that's
not the case - that is all automated.  The build is done on some
machine (baremetal, and in this case it happens that it was one of
these same machines) and generates build outputs including all the
modules.  Then the target machine is completely wiped and reinstalled
from scratch, and the kernel and modules from the build are unpacked
onto it and a suitable initramfs created (using the standard Debian
tools for such things).
