I tried to describe that these are two separate things, namely:
1. The arbitrary limitation that if your computer 'only' as EFI32,
Apple prevents you from booting into the 64-bit kernel.
2. For the set of computers that Apple enables the capability of
booting into the 64 bit kernel (namely Intel Mac's with EFI64
firmware, and perhaps some other limitations), only a limited subset
currently boot by default into the 64-bit kernel.
I don't think you understood me. I'll restate it more clearly: there
are some EFI64 Macs which will not load the 64-bit kernel even if you
attempt to override the default choice by pressing "6" and "4" during
boot. Thus, EFI bitness is clearly not the only criterion, if it is
one at all (we outsiders have insufficient information to know whether
it actually is, IMO).
