Speaking of which, I ask this from time to time: What's the minimal patch set that _just_ adds -SKAS0 mode to something like a 2.6.11 kernel? I'd like to try it out, but every time I sit down to whack at it my interest budget runs out sifting through a mountain of unrelated x86-64 patches to try to figure out what exactly I need to apply to get just SKAS0... No biggie. I'll can always ask again later... :) Rob ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
