Hi Xavier, My recommendation is to resolve the kernel.org bug as won't fix and update the Ubuntu MacBook Air wiki on https://help.ubuntu.com/community/MacBookAir with details linking to use of UEFI install.
The Mac does not require secure boot. There is no loss of functionality. You will need to use rEFInd, and follow the instructions for EFI boot. Since you are already dual booting you should be able to boot into MacOS, this time reinstall rEFInd for EFI booting. Make your EFI based Ubuntu USB image and reinstall Ubuntu.
