Subject: Re: [PATCH] Fix e820 end address with EFI

I was able verify the kernel that does not boot on the MacBook (vanilla 
2.6.29-rc4) does call efi_ioremap() which bails out early returning 
NULL. So no remapping happens in this case.  I have no idea if 
efi_ioremap ever does succeed in mapping any ranges though being I have 
no video or console this early in the boot and have to rely on triple 
faulting as a means of debugging.
