Wanna bet?

Could you test if the attached patch works for you on newer Mac? Note,
that it still does not detect EFI bootable USB stick if it is inserted
before power on - only when you stop in boot manager and insert stick.

It also still does not boot from the second (unknown) EFI suggested for
CD. But this second choice is also present only when CD is inserted
before power on - it is not shown if CD is inserted in boot manager.

I also do not get "Windows" menu choice on USB. May be because there is
no active partition.

Merry Christmas to everybody!
