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.
