That is, in *YOUR* usage context they're not. I had to parse what you wrote a few times before your comments about $SUBJECT started to make sense. I've *never* heard "host" used that way, and rarely hear "platform" used that way either.

Both i386 and x86_64 are clearly an "arch". They even live in an "arch" directory: linux/arch/{i386,x86_64}.
When folk talk about a "PC Platform", they're talking about a thing that doesn't quite exist in today's Linux tree. If we ever get to an arch/x86, that could have a plat-pc (or mach-pc) subdirectory. ThinkPads should then be a variant of that.

As a rule, there needs to be a Good Reason to create a new bus type. A "feel" is a pretty weak reason...
