That is certainly a good way to get off the ground; two or three LEDs
normally gives you just enough to get into the initialisation in the
kernel and have enough for an LED to tell you if it got to a particular
point.
Then hacking the printk code in kernel/printk.c to force output very
slowly with big delays out of your serial port lets you get everything
else going before you get the full serial port stuff written.
