Greg Kroah-Hartman has put the slides and a transcript to his keynote at OLS online. The title speaks volumes:
"Myths, Lies, and Truths about the Linux kernel". He starts off:
"I'm going to discuss the a number of different lies that people always say about the kernel and try to debunk them; go over a few truths that aren't commonly known, and discuss some myths that I hear repeated a lot."
