This is actually a *NIX network, bunch of debian, opensuse, etc. I'm trying to set it to the lladdr range reserved for xen (00:16:3e:xx:xx:xx). I've even tried setting it to its current address (FE:FF:FF:FF:FF:FF).

What lladdr are you using? You aren't trying to set a global or
broadcast address are you? I know windows insists that the 'local' bit
is set in the mac address.
