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
  does)
- 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)
