The A20 gate patch was to make sure GRUB works on the Intel Mac.  The
old way to enable the A20 gate is not present anymore.  So this patch
is also required when using the Intel Mac, but unrelated.

The SMP issue can be avoided from GRUB when you press the "right
arrow" key instead of "enter" to boot.  Someone mentioned this on the
mailinglist, perhaps that is why you mixed up the two?

Thanks,
Marco
