Remove gratuitous waste of 2K of memory for BIOS variables. We never load
the kernel at 0-640k; we haven't had the ability to do that since before
2.0R. Furthermore, I fail to see how putting an instruction at 0 and then
doing a .org 0x500 is going to prevent the stuff from getting clobbered
in the first place; a.out is just too stupid to know about sparse address
spaces.
