there is a two pin 5V connector, between the CSI/camera connector and
the expansion connector, which should be fine to run a 5V fan..  check
which pin is +5 and which is GND with a multimeter before hooking
anything up.

what branch?  what kernel cmdline?  what config?

I have a random semi-recent upstream kernel here, which does boot:

https://people.freedesktop.org/~robclark/tmp/ifc6410-boot-upstream.img

you can check the cmdline and /proc/config.gz to get the config I was
using, and use those as a starting point
