Now that you put it that way, as a matter of fact, perhaps...

Cool. =:^) I don't remember whether I mentioned that I'm a gentooer or
not. That means I build everything and get the advantage of pre-build
configure options as gentoo USE flags, etc, but the process is somewhat
automated, making it much easier to keep up with updates, etc.
That's /my/ ideal balance between customizability and practicality, but I
definitely respect anyone farther out toward the LFS end than that. I
could certainly do it for a first installation, but I don't expect I'd
keep with it for the now almost exactly a decade I've been on gentoo.

That /is/ interesting.
The log files I alluded to above aren't exactly kde, but...
As suggested by the location and name, this is the output/error log for a
user's X session. Maybe you'll find something there.
This is the one your log comment triggered my memory of, and I'd guess
actually more likely to provide details on the problem. On a modern
Linux system and xorg, input devices are hotplugged. This log from xorg
is the most likely place to find reports of any X related problems
including input device hotplugging issues and any time X doesn't behave,
this is the first place to look.
I think you have a good chance of seeing something there, particularly
since you said it was kernel sensitive, meaning it's likely an xorg
hotplugging issue, not necessarily a kde issue. Note that the hotplugging
involves udev as well, so you may ultimately trace it down to a udev
compatibility or configuration issue.

That would be very much appreciated. I'm running 3.13 plus now (actually
some way into the pre-3.14-rc1 commit window running a git kernel) and
haven't had myself or read of any such issues apart from yours, and now
you have me really quite curious what is going on in your case, so
updates once you have them will be much appreciated indeed! =:^)
