This limitation is mostly irrelevant because Debian only supports 64-bit
UltraSPARC, so the only case we have to worry about is the disk from an
older to a newer machine.

As for the original question, I can't speak for sure, since I'm not a
SPARC porter, but it only seems logical that a 64-bit kernel (which,
again, is what they all are in Debian) will be able to address more than
2GiB of swap.
