Apologies if this suggestion is total arse - my arping/network foo is
reasonably weak. But just in case this helps...

Could there be, for some reason, a machine on the switch that has been
spoofing the phantom MAC address? I know we were left scratching our
heads a while ago when we forgot that we had spoofed MAC addresses on a
machine (for totally legitimate reasons *cough*).
