Did a buildworld/buildkernel and installkernel/installworld, and
installed new loader.rc from the source tree, but with the new boot
loader, both new and old kernels panic at the very beginning of the boot;
Ctrl-Alt-ESC didn't work. The last working boot/world/kernel is from
2003-11-08, and kernel config file hasn't been changed since then.
