I've got the same machine and exactly the same problem. Fortunately I
found a way using tapeboot by putting the different segments on different
tapes. Bug in tapeboot?
Perhaps you might try to boot your sun via NFS. I've got it running
booting from a FreeBSD server with a patched mountd.

BTW: there is another problem concerning the tape driver. Any time
a SOFT ERROR occurs, NetBSD panics with "done > todo".

        if (sense->error_code & SSD_ERRCODE_VALID)
                info = _4btol(sense->info);
        else
                info = xs->datalen;     /* bad choice if fixed blocks */
        if ((sense->error_code & SSD_ERRCODE) != 0x70)
                return -1;      /* let the generic code handle it */
        if (st->flags & ST_FIXEDBLOCKS) {
                xs->resid = info * st->blksize;
<<<<<<<<<<<<<<<<<<<<<

So if (sense->error_code & SSD_ERRCODE_VALID) == 0 and
      (st->flags & FIXEDBLOCKS) != 0,
xs->resid will be assigned to xs->datalen*st->blksize! I inserted an
if-statement and now it works:
>>>>>
        if (st->flags & ST_FIXEDBLOCKS) {
		if (sense->error_code & SSD_ERRCODE_VALID) /* <---- */
                	xs->resid = info * st->blksize;
