As do I.

I'd prefer we cleaned up the entire EFI code to do this and a few
other things differently --- however, given the status of 2.4.x I'm
not sure this is desirable?

Given that is this acceptable for 2.4.x as-is or should I move the
code into the driver as distasteful as that is.

I'm not convinced that massive EFI API changes right now are a good
idea (not to mention I certainly have no time for them myself).
