Yes, should work. But if you want to paint them side by side, printing a
new one after booting the next processor, things get a bit tricky. You
have to do cursor positioning (possible with printk?), and keep in mind
that everything what you prink() will appear in the message buffer, so you
could confuse klogd and friends with that. You could have a serial
console, ...

There a few things more you have to think about. But as I hav'nt a SMP
box, someone else would have to do this job :-)

Hmm, took the current 64x64 logo, scaled down do 16x16 (that would fit
into two chars)... Bad idea, hardly to recognice as penguin, _very_ small.
