Right. We need to find out what, exactly, is failing to make progress. I
have exactly one guess as to what might be going on, and it's a long shot
at best. To gather more evidence, I need to know if the kde thing that's
segfaulting is accessing /dev/pass* or /dev/xpt*. If you can confirm that
it is, then we'll need to see how to fix that.

Also, you'll need an installworld as well as an installkernel so the new
headers are installed prior to running kde. If that fixes it, then my guess
goes from a long shot to close to a sure thing.
