Why wouldn't your /boot work with GPT ? It works for me

Yes, but it requires a "BIOS boot" partition for the core image (usually 
less than 100 kB, so 1 MB is plenty enough). Also some flawed BIOS 
require that a legacy partition entry in the protective MBR has the 
"boot" flag set.

Legacy boot on GPT has some requirements, but it works.
