Is this related to things like:

  isp0: invalid NVRAM header

where the built-in sparc64 hardware doesn't include the ROM/NVRAM normally
associated with some chipsets?  As there is nothing mapped at that location,
we get the data fault?  I wonder if that is also the case where this value
appears to be unset, but that hardware is more forgiving.
