I made a new kernel (make kernel) and since I never set such an option
anywhere, I'm pretty confident, that it's at its default value.

Thank you! That worked, I still am running the kernel with the change
you mentioned earlier, though.

I noticed this in dcons_crom.c
#if __FreeBSD_version >= 500000
static int force_console = 1;
TUNABLE_INT("hw.firewire.dcons_crom.force_console", &force_console);
#endif

Which to me looks like the default is to force the console, even if
NOTES has this default
./conf/NOTES:options    DCONS_FORCE_CONSOLE=0   # force to be the primary console

Anyway, let's turn on ULE and PREEMPTION and see what happens :)
