Guess it might be broken.

Who has actually tested efi graphics, and on what hardware?

Does it clear/reset graphics before it hangs? If not we could perhaps
add some debug prints to find out what it is doing before the hang.

I could perhaps try the efi graphics driver on some iMacs later
this/next week (depending on the location where you are reading this).
