Hi Antonin

The problem is in the VGA configuration and FB configuration you need
to pass the -serial stdio flag to QEMU.  VGA and FB only makes
sense for OK Linux, OKL4 itself only supports serial I/O.

Hence, I think the system actually booted fine, but the console output
was lost leading to the image of a "hung" system.

Let us know if that works.
