Adding nomodeset fixes this on my Dell Inspiron 500m with a 82852/855GM
and a 1400x1050 display, running kernel 2.6.31-15-generic and Xorg from
the xorg-edgers ppa (xorg 7.4+3ubuntu10 and intel driver 2:2.9.1~git-
0ubuntu0tormod).

With KSM, watching a DVD with Totem, the framerate goes down to almost 1
fps. VLC is almost ok, 10% of frames dropped with 100% CPU load.

Without KSM, VLC is perfect but Totem goes nuts: viewing a DVD works
sometimes when using a small window, but never full-screen. It looks
like the UI is on top of the video.

Also, I think disabling KSM caused another problem: when waking up from
suspend-to-RAM for the first time, the display resolution came up lower
than normal, and playing a DVD with VLC on XVideo caused a hard lock-up
- not even Alt-SysRq-K,S,U,B could boot the machine.

I tried suspending again manually after rebooting, and now it worked
correctly. The lock-up occurred after the laptop had supended
automatically due to being idle (I've set a 30 minute timeout for
suspend). I'll keep an eye on the issue and see if there's a specific
bug report for it.
