I'm not exactly sure what's wrong with the buffer - whether it's a case
of not being able to access it properly or somehing buggy in the EFI
code for reading files. No fault occurs when reading into it, it just
doesn't contain the correct data.

Either way, I'm going to leave your patch as-is and just ensure I fix
this before the merge window. I think it's a good idea to have whatever
workaround we come up with documented via an entirely separate patch.
