The problem happened even wiht DHCP. I set it static in order to
get around/diagnose the problem.

yep. I built a nodebug kernel first of all, then rebooted, then started
make buildworld.

It worked while the edk (?) part of it worked, then it didn't work at all
once FreeBSD had booted multiuser.
I was able to make it (the fan) work by installing
https://github.com/aphor/FreeBSD15-RPi5-modules.git and following the 
instructions.
