There is a bit more out there including Aurelien's excellent write up
and older Debian images here:
https://www.aurel32.net/info/debian_arm_qemu.php
https://people.debian.org/~aurel32/qemu/armel/
However the web is transitory and git is forever so lets add something
to the fine manual.

same remarks as for other patch.
Does the 'make' make the right dtb automatically, by the way?
(I have some notes where I had to tell the kernel to build the
dtb explicitly, but maybe they are out of date.)

It's a bit daft that these aren't in the defconfig, but hey.

I didn't do anything special and it was there in the build directory. Do
your notes pre-date 2013:
