Where the broadcast bit is zero, and the server is capable of
unicasting without ARP (the client will not reply to ARP yet), it
constructs a packet with the destination MAC equal to the client's
chaddr, and the destination IPv4 address set to the 'yiaddr', the
offered address.

Where the broadcast bit is one *OR* the server is not capable of
unicasting without ARP, the server uses the all-ones destination
ethernet address, and all-ones destination IPv4 address.

I have no reason to believe that a Debian 3.0.4"-13" server would
not fall into the first category, sending unicasts without ARP, since
it makes use of the 'LPF' socket mechanism.
