It depends. Sometimes the bisection can be done in qemu/kvm/xen or

similar tools.  At least if the problem is not too hardware

dependent. And more and more people actually run in such environments.
I can also do it faster with autoboot or nfs root/powerswitch, but

admittedly that's a very specialized setup most people don't have.
Still I agree with your basic point that it should be only

last resort.
