Hmm..., I see that linux_write has the same problem:

        size_t                  write_length = count * dev->sector_size;
          ...
                if (posix_memalign(&diobuf, PED_SECTOR_SIZE_DEFAULT,
                           count * PED_SECTOR_SIZE_DEFAULT) != 0)
          ...
          status = write (arch_specific->fd, diobuf, write_length);

another patch coming up...
