So far, nobody was foolhardy enough to do it in any distro or upstream. Users do, but they do it *after* they tried it manually and therefore they know if it will work right or not in their setup. I think it is best to just leave it to default Y for a few more months, while I get more reports about where it works well (and how well). I know it is a lost cause on very new thinkpads, but what I really need are reports on the older models, which I don't get as often as I'd like. Maybe we can make it default to N for 2.6.26, along with a big fat warning on the Kconfig and at runtime that I need reports on Axx, T2x, X3x, R3x, otherwise I'll just rip it out for 2.6.27... -- "One disk to rule them all, One disk to find them.
