Unfortunately, thinkpad x60 does not boot with acpi=off (should we add another test to linux firmware kit? Machines should still boot in acpi=off mode...). acpi=off noapic nolapic nosmp makes it boot, and that in turn makes kjump work. Screen is not refreshed on kjump back to original kernel, but I guess that's to be expected. I did not play with framebuffer, yet. Maybe it is time to move kjump functionality into -mm and kexec-testing?
