    It isn't actually a crash - X comes up fine, just without direct
    rendering (which really kills KDE4 performance).

    Thanks - I'll give this a try tonight. As to your other emails:

    > hm, could you send me the config that triggered this?

    I will do so tonight when I am home again. It is a UP AMD64 box with
    a VIA chipset, if that helps.

    Good to know - I will get the commit ID tonight as well, although
    wouldn't following the same bisection sequence that I did give you the
    same bisection point? I guess that would assume that linus/master and
    auto-x86-next haven't changed much since last night, which might not
    be correct.
