...except convincing the driver to use it.

Or does -current have some uniform way to do that now?  As of
ifconfig.8 1.53 (the most current I have at ready hand), I don't see
any option for it - perhaps it's not in ifconfig.

Until relatively recently (roughly, until they started using commodity
PCI NICs), Sun NICs didn't have addresses in eproms. Sun _machines_,
not _interfaces_, had MAC addresses - which is where I started this
subthread off.
