It's definitely related to desktop effects, I am totally lockup-free without them, but will reliably freeze the instant I turn them on (alt-shift-f12).
However, I am also plagued by bug 342923 which makes performance pretty awful and with screen corruption. I wonder if these two bugs are related somehow.
I was running KDE4.2 from the PPA packages on intrepid before jaunty, and there were no problems at all. The intel Xorg driver has my finger pointing at it.
