FYI:

After a lot of digging trying everything, I found that the pxeboot and 
loader.efi was too big simply due to ZFS support.

So I did this after buildworld:

cd /usr/src/stand
make WITHOUT_LOADER_ZFS=YES clean
make WITHOUT_LOADER_ZFS=YES all
make WITHOUT_LOADER_ZFS=YES install

And now it works, with my old GigaByte mainboard!

Why should pxeboot have ZFS support?
