Splitting the array will only work if by that you mean having multiple 
arrays (showing up as separate "disks"), one of which is <2TiB.  The 
problem isn't that grub has a problem with >2TiB disks directly, it's that 
you can't use an msdos disk label on a disk >2TiB -- you must use gpt.  
And neither grub nor lilo understand gpt disk labels.
