OK, there is one more thing which I sadly have to use on my Lenovo
T420. See the inline patch and attached patch.
I end up doing xen.efi -basevideo -mapbs -noexitboot

Subject: [PATCH 2/2] EFI/early: Implement GetNextVariableName and /query and
/noexitboot parameters
In the early EFI boot we will enumerate up to five EFI variables
to make sure it works.
The /query will just enumerate them and then quit. Helps in
troubleshooting and redirecting the output to a file (xen.efi /query > q).
The /noexitboot will inhibit Xen from calling ExitBootServices.
This allows on Lenovo ThinkPad x230, T420 to use GetNextVariableName
in 1-1 mapping mode.
