Correct.

That will work. Another way is to see if the raid-controller can present two 
volumes from your raid5, one small (for OS) and one big (for gpt large fs). 
If this works then you'll get one device on which you can use msdos 
partitions and boot from and one (>2T) on which you use gpt (or simply lvm 
directly on the device).
