Yes, this is what I need to debug next. I had hoped for one of the kernel
people to chime in and give me a hint what we might be missing here.

Geert, maybe?

The falconide isn't a platform driver with proper MODULE_ALIAS()  yet,
so its module needs to be loaded based on platform heuristics.
Recent Debian may no longer have those?

Do you have

CONFIG_DEVTMPFS=y
CONFIG_DEVTMPFS_MOUNT=y

?

That's the hint I was hoping for :-). Thanks a lot!

I will look into this.

We're missing the latter:

root@pacman:/boot# grep CONFIG_DEVTMPFS config-4.12.0-1-m68k
CONFIG_DEVTMPFS=y
# CONFIG_DEVTMPFS_MOUNT is not set
root@pacman:/boot#

Could that be the root of this issue?

It wasn't needed with QEMU, so I doubt that it is needed with Aranym. 
systemd seems to have mounted /dev regardless. I mentioned this in the 
other thread:

# grep devtmpfs /proc/mounts
devtmpfs /dev devtmpfs rw,relatime,size=500196k,nr_inodes=125049,mode=755 0 0
