Hmm, after I did a 'sudo idown usb0' first it works:
tingo at kg-home:~$ sudo ifup usb0
* Stopping NTP server ntpd
tingo at kg-home:~$ ...done.
* Starting NTP server ntpd
...done.
(the ntpd part looks scary)
Hmm, when I replug my Freerunner, this is what happens:
tingo at kg-home:~$ ifconfig usb0
usb0 Link encap:Ethernet HWaddr 00:00:22:55:bb:00
inet6 addr: fe80::200:22ff:fe55:bb00/64 Scope:Link

tingo at kg-home:~$ sudo ifup usb0
ifup: interface usb0 already configured
tingo at kg-home:~$ ifconfig usb0

Huh? where did that IPv6 address come from?

I still don't know why the Freerunner gets a IPv6 address, but the above works:
tingo at kg-home:~$ sudo ifdown usb0
RTNETLINK answers: No such process
tingo at kg-home:~$ sudo ifup usb0
* Stopping NTP server ntpd
tingo at kg-home:~$ ...done.
* Starting NTP server ntpd
...done.
tingo at kg-home:~$ ifconfig usb0
usb0 Link encap:Ethernet HWaddr 00:00:22:55:bb:00
inet addr:192.168.0.200 Bcast:192.168.0.255 Mask:255.255.255.0

It did - many thanks!
