Actually, there is, but it isn't constant.  slices need to be an even
number of 'cylendars' in the fdisk label.  Some BIOSes use this to
determine the geometry of the disk.  Some BIOSes have issues booting
when these numbers are correct.  By making the the partition size
different, the BIOS was able to properly grok things and booting
worked.
