As posted elsewhere, with all 3 discs connected and grub-install run 
against a GPT partition, on reboot I can see the two MBR discs and not the 
GPT disc.

Because core.img has been built with part_gpt I can't see the partitions 
on either MBR disc.

However this does point to the main issue - that it isn't part_gpt causing 
the problem but something that is preventing core.img seeing the GPT disc.

I will follow up on BIOS/UEFI issues this morning.

I note that the version (1.99) of grub2 is quite old - this is the version 
that ships with the latest version (12.04) of Ubuntu.
