--- Comment #2 from Breno Leitao <breno.leitao at gmail.com> ---
I was able to try one patch created by Leandro earlier today and, with his
patch, I  am able to pass this part.

ums0: <Mouse Interface> on usbus0
ums0: 3 buttons and [Z] coordinates ID=0
Sending DHCP Request packet from interface bge0 (98:be:94:05:2c:4c)
Received DHCP Ack packet on bge0 from 9.8.234.81 (accepted) (got root path)
DHCP timeout for interface bge1
DHCP timeout for interface bge2
DHCP timeout for interface bge3
bge0 at 9.8.234.221 server 9.8.234.81
subnet mask 255.255.255.0 rootfs 9.8.234.81:/var/nfs/ufs 
Adjusted interface bge0
Shutdown interface bge1
Shutdown interface bge2
Shutdown interface bge3
Trying to mount root from nfs: []...
NFS ROOT: 9.8.234.81:/var/nfs/ufs
..

Later it crashes on a different topic, which seems to be related to the file
system. I am not sure if the problem is related to my rootfs  being buggy
somehow..
