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.

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.
