Well, I tried and put this line into /boot/loader.conf, but the result
was endless boot loop. No idea what is wrong... it just quickly loops,
most probably inserted line is causing system reset.

No, there is no such file in /boot/kernel at all.

is the same - est could not attach, because CPU is not recognized.

On another system, with different Intel CPU, it works.
