Sure, at this point you had completed step 8 at http://www.coreboot.org/Lenovo_x60x
Now I thought things wouldn't be critical anymore... Then I run bucts 0, didn't save the output (damm). then I shut down the system
So you skipped step 9 and went straight to step 10.
then pressing of the power button result in endless beeping stop that the first time quiet early... Do I have a beeping brick now?
Yes. Since you skipped step 9 the last 64kb of the flash chip are still from the factory BIOS.
Disassemble the machine and use an external flash programmer to write a full coherent image to the flash chip, either your factory BIOS backup or the full coreboot image.
