Now that I think on this a bit more, a sysctl might be a better place to put this, but it seemed to belong with the i386_vm86() bits, rather than polluting initcpu.c right away. Mind you, if you're going to hack perfmon, perhaps putting this in initcpu isn't such a bad idea after all, with a loader tunable instead. That way perfmon can pickup on the tunable when attached by nexus during boot. A few people want to see i386_vm86() die. Its death is inevitable given x86-64 and the other new platforms. So perhaps the other way is better. In any event, I reconsider my decision to commit the code, and simply offer it as an example of one way to do things, not necessarily the right way.
