In fact i was too impatient, it did boot. After the last witness warning 
these messages appear:

tx0: Ethernet address: 00:e0:29:6c:2e:47
tx0: [ITHREAD]

tx0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
         options=8<VLAN_MTU>
         ether 00:e0:29:6c:2e:47
         inet 172.30.1.100 netmask 0xffff0000 broadcast 172.30.255.255
         media: Ethernet autoselect (100baseTX <full-duplex>)
         status: active

And it does work
