32 bit kernel on 64 bit CPU

So you cripple your other two machines to satisfy one?
Sure, that's reasonable. It's like having a 10G disk drive and a 15G disk drive and not using 5G of the larger drive so you can use them as a mirrored pair.
I too maintain a single kernel binary that I run on lots of systems. Many of them even access the same actual file, over the network. Some are capable of running 32 or 64 bit and others only 32 bit. The extra speed I'd get out of the 64 bit machines, in my case, would not justify the extra maintenance effort of having two kernels.
And note that there's no hypocrisy here. I never intended to have full x86_64 speed when I acquired the x86_64 machines; That feature is just an unwanted by-product.
