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.
