32 bit. Call me the day an affordable 64 bit machine is available (I mean
for home user/hobbyist). No Apple machine has ever had a 64 bit processor
to start with.

Note that actually running the kernel in 32 bit mode makes sense
on 64 bit processors since the code is smaller (building addresses is much
easier and does not require a TOC) and there are fairly simple and cheap
MMU tricks to access all memory if needed (playing with segments but this
can be kept local to a given CPU, so no locking is necessary).
