Thanks, Peter
Looking into efivarfs it seems to use the functions that I looked at in efi.h so I guess I am misinterpreting the 1024 bytes limitation in the comment (either that or you are mistaken ;-) ). I need to access the variable from within a device driver so using efivarfs does not feel like the way to go here.
