Ethernet is a broadcast protocol, not point to point, even if you do
only have two hosts. The IP layer may be able to figure out the right
settings itself, or then again it might not.

OK, so Linux knows that eth0 isn't really a point-to-point interface,
and issues ARP requests ...

Don't know what this is offhand, but it's not ARP. You don't specify
the MAC addresses in use, so I don't know which way it's going either.
As it's nearly a minute since the original ARP request, it's probably
not related to it.

75 seconds later, and the Linux box is still issuing ARP requests.

Your Windows box isn't answering the ARP requests. You don't know
whether or not it's receiving them in the first place, unless you can
get tcpdump or similar on the Windows box.
