Raspberry PI with 512 MB does not boot FreeBSD?

Due to the very welcomed help from Bernd Walter, who supported me with an
USB serial adapter for the Raspberry PIs serial console , I have an answer
now: The console shows simply nothing.

The serial console and the USB serial adapter are fine because booting an
Raspbian "wheezy" image showed the Linux boot messages.
