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). Indeed, my guess is that (on machines that are actually 64-bit capable) it has rather more to do with not having 64-bit versions of some of the required device drivers...

We are still processing some projects, and did not want to hold up the bulk of the release, so the following projects are coming later: Getting access to the source code of CF (Lite) would help checking if it's possible to work around the CFMessagePort 32/64 -bit bug in 10.6 without having to wait for a system update. It's really useful to have access to all the open sourced part of Darwin the earliest possible. For instance when Apple made the move to Intel, having access to the db source code helped work around a byte swapping bug in Mac OS X without having to wait for a fix in a system update (which eventually came).

Booting by default into the 32-bit kernel for the next couple of point releases for maximum compatibility makes total sense. 1 is more of an arbitrary limitation, with no technical reason for it.
