No, I'm using uboot from the device manufacturer.
Should I use Arago ?

Thanks again, ubldr started after I applied the patch.

Number of U-Boot devices: 1

FreeBSD/arm U-Boot loader, Revision 1.2
(root@intel.bsdpad.com, Fri Oct 19 22:50:42 UTC 2012)
DRAM:			 1023MB

Device: disk

Device: net
net_probe: no network devices found, maybe not enumerated yet..?
netboot: couldn't probe uboot_eth0
[...]

Verbose help not available, use '?' to list commands
loader>

seems my u-boot don't see ethernet, but I think it is not a big 
problem for now.
