Re: [PATCH] bug fix for x86_64 efi

[Peter Cros]

Tested the patch applied to rev 1996 for grub.efi 64 bit and 32 bit, on Imac81 (4GB ram), MacBookPro41 (4GB and 2GB ram)  MacBook21 (i386)

with Macosx 10.4 10.5, ubuntu810.

All good.

64bit Macs have other ongoing EFI problems with linux kernel initializtion and keyboard.
