Actually on Slackware 13.1 I already changed
versions of:
-xf86-video-intel: 2.11.0 to 2.9.1, because 2.11.0 is unusable with
Trinity and KDE 3.5.10
-Mesa: 7.8.1 to 7.7.1 because 7.8.1 has a huge performance regression
with one of the OpenGL games I play
so I know that they are built from pristine sources.
In general Slackware applies very few patches to upstream sources.

I have driver
crashes:
-under Slackware 13.1, as soon as I enable KDE 4.4's KWin effects.
(I use Mesa 7.7.1 as 7.8.1 has a severe performance regression with
StepMania)
-under Slackware 13.1, after too many cycles of suspend/resume
(highly variable)
-under Slackware 13.37, when using KDE 4.5 with or without KWin
effects, after at least a half dozen of hours (highly variable)
-under Slackware 13.37, when I play a Xv-accelerated video, then
open an OpenGL game, then close it when the video is still playing
(often)
On my AMD laptop, with FOSS drivers, I can simultaneously have KWin
effects, play a video and launch a 3D game without any crash and
with reasonable preformance.
Have you tried your Intel card on any distro but Slackware? Also,
have you tried any desktop besides KDE4? It might be a glitch in one
of the Slackware packages (either a recompile of the driver or trying
on another distro could tell), or one of the glitches in KDE4 (I seem
to remember having a lot of crashes in KDE 4 on several different
cards, though I haven't used it since 4.6 and I hear that 4.8 is
supposed to be fairly stable). I never got around to trying out
Slackware, so I wouldn't be able to test the driver or KDE 4 from
within Slackware on my machine. There is
a FOSS radeon driver for which some developers at AMD
are paid to work on it, and on my experience it works OK both
for light 3D games and KDE4 compositing (even better than AMD
proprietary driver for the latter). And compared to Intel
drivers I've almost never seen it crash.
I'm using an Intel card right now (same one since December 2009)
with the FOSS Intel driver. I've never seen any crash cause by
the driver, all crashes thus far were either a glitch in some
program that overloaded my CPU, or from overheating (though this
usually leads to a kernel panic rather than an X.org crash).
Of course, I rarely run anything that requires 3D acceleration.
Purely for comparison purposes, on my Debian Squeeze install, Intel
driver, Intel Mobile Series 4 Integrated Chipset (includes my video
card, as is usually the case with Intel): -I never tried any of the
special KWin effects in any KDE version, nor Compiz (never really
cared much for eye-candy) -I can suspend to RAM and resume countless
times without problems aside from impatient programs that don't want
to wait for my network manager to reconnect ;-) (I never tried
suspend to disk) -I can run my computer full-power almost the entire
day without a crash (unless you count the random crashes the occur if
I inadvertently block the fan). -I've never heard of Xv-accelerated
videos before, though on many occasions, I've had a lot of stuff
running at once (including either a DVD or Youtube video) when my
screen saver activates, and a few of those times, it was one of the
OpenGL screen savers.
Xv is basically the acceleration every video player is using
to rescale
the videos and/or do RGV->YUV conversions.
But apparently you don't have the same generation of Intel hardware
since I have a Core i3.
