I think the reason is that since r185059 the isa(4) hints (in this
case the default one for le0) are now also applied to acpi(4).
Even previously reserving the device unit number corresponding to
the hint (i.e. le0 for hint.le.0.at="isa") regardless of whether
it's actually present and enabled or not was the expected beaviour
AFAICT, although limited to the presence of a ISA bus.
