Hm. From this message am I make a correct assumption that the
service provider is providing the machine? And if he has had the
same problem with someone else, I suspect the hardware he is using
is a common denominator.

Wrong assumption. Different OSes treat hardware differently and
just because things work on one OS does not mean they will work the
same on another. Usually it "It works om MS so it must be good"
but in your case it could be the drivers for the un-named NIC card.

BSD is very very stable - but shows up some hardware problems
rather quickly.

What NIC?

>3 What good will "an static arp entry to the switch" do?

Keep the route up if something stops it. I've seen some weird
things when a net connection on OS/X would do all sorts of weird
things if the switch had a problem or there was a minor
connectivity problem, and a reboot would re-write the Apple
modified Apache httpd config files and turn off all the sites.

With a static arp entry the MAC address will always be mapped
to the same IP. This method is often used for setting up things
such a print servers. You access them by mapping an IP to the MAC
address and set that in the server. Since all communcitions is
done MAC to MAC it's quite handy.
