I've managed to track down the proxy arp problem in 3.2-stable. It was due to 
misalignment which led to wrong/corrupted destination address and netmask.

In many scenarios, the wrong address and netmask would match a existing route
in the routing table, prompting the kernel to reject the request to add the
new route.

To fix the proxy arp problem, type:

  fetch -o - http://www.daddylonglegs.com/arp.patch | patch -d /usr/src

and then rebuild arp in /usr/src/usr.sbin/arp.

kt :)
