Dunno.  All my rEFIt says about itself of substance in that "About 
rEFIt" is that it's version 0.9.  Is yours one of those newer ("Santa 
Rosa") MacBooks that require at least refit 0.10? (I think it's because 
those firmwares require 64-bit EFI image)

[rEFIt] "Version 0.10 (June 14, 2007):
    * Supports the new “Santa Rosa” generation of MacBook Pro models.
    * All binaries built as “fat” 32-bit and 64-bit. (May not work on 
non-Apple EFI firmwares.)" http://refit.sourceforge.net/history.html

But we (GRUB) aren't refit -- we just need to know that we can't use 
that kind of multi-arch image to support all x86 and x86-64 EFI platforms.
