er, my mistake ... i *used* to leave a 1MiB gap, but as long as the
default unit is MiB, and you specify offsets using simple integers,
parted will automatically start/end on the correct byte:

(parted) u mib
(parted) mkpart pri 1 129
(parted) mkpart pri 129 641
(parted) p
[...]
Number  Start    End     Size    File system  Name  Flags
 1      1.00MiB  129MiB  128MiB
 2      129MiB   641MiB  512MiB

(parted) u b
(parted) p
Number  Start       End         Size        File system  Name  Flags
 1      1048576B    135266303B  134217728B
 2      135266304B  672137215B  536870912B
