If they changed, it doesn't matter. Begin is a 10-bit field
and cannot hold values of 1024 or higher.
This silly fdisk you are using prefers to store (start % 1024) there,
and conversely prints not the value of begin, but begin+1024*(start/1024).
Everybody else stores min(start, 1023) there.
The value that is stored is not used by Linux.
