Please verify this. What version are you using? In 3.0_BETA and -current
at least it should (a) just work, and (b) fall back to the global address

Does your switch maybe hardwire the MAC address and refuse to overwrite it?

There is none - it has been proposed several times, but all drivers need to
be changed to support it (which is easy for all sun drivers).
