That should work, I believe.  (But obviously doesn't and ought to be 
fixed, though I haven't looked into it.)  Did you try booting a 64-bit 
Linux to see if that works?

That shouldn't work (the EFI library-functions provided by the MacBook 
are specific to 32-bits or to 64-bits, 64 in the case of your machine).

My MacBook (Macbook2,1 -- mid 2007) has 32-bit-EFI and 64-bit-processor, 
and I've successfully run both 32bit and 64bit Linuxes on it, although I 
tend to boot them via grub-BIOS (depending on Linux versions etc., EFI 
booting seemed to go wrong in various ways in the past when I tried it)
