Unless I've been fooling myself, it's possible now. Just stop the boot
loader during loading by hitting the spacebar and type
at the loader prompt
This requires that you have saved the /boot/kernelname subdirectory
beforehand, for example
cp -r /boot/kernel.old /boot/kernel.spare
and, on an RPI2, that you have serial console access.
It would be very convenient if this were possible on the video
console, I gather it's a non-trivial modification. I'm unclear
on the situation with other architectures.
