So, I've used u-boot from ports (u-boot-orangepi-one) and it boots 
(using dd if=u-boot-sunxi-with-spl.bin of=<disk> bs=1024 seek=8). Guess 
I won't find out what the differences were, but so far I don't care. Was 
able to use the .dtb I've compiled from the GNU .dts files I've copied 
over from the latest linux kernel source tree. Was a bit of macking 
around to get the build through, but. Now I have a fully working system. 
Except ZFS is not working yet ;-)

Thanks for the pointers,

Mat
