How hard would it be to make this a compile time option? Small memory machines are unlikely to want to use 4 MB pages anyway. In other words a configuration option that would disable 4 MB pages and put the kernel at its current location when set one way, and would enable 4MB pages and relocate the kernel on a 4 MB boundary when set the other way. I really dislike our default configuration of a little bit more speed at the expense of data integrity. If that's what I really wanted, I could probably get even more speed by overclocking.
