This mail doesn't has an attachment and the previously attached kernel
log had the nvidia module loaded. So there is a misunderstanding
somewhere (or you just forgot to attach a recent kernel log?).

Can you install older kernels and check if this gives you a working
setup again? Please tell if you need instructions to do so. It would be
interesting to know the newest kernel that still worked and/or the
oldest broken kernel.
