Well, the good news is that I can now boot a legacy bootloader from grub2-efi.

The not so good news are:
- I still cannot choose which device I boot from :-/ (I think I'll have to
  modify the BBS table priorities to do so, though the CSM specification isn't
  very clear about this, but it seems that it's what the BootCamp application
- the disk controller is still put back in IDE mode (whereas it's in AHCI mode
  when the machine boots, and stays in AHCI mode when booting a EFI OS, so I
  guesss one of the CSM drivers is responsible for it)
