I am also on a Dell C400 running Kubuntu Jaunty. I can confirm that starting with a blank xorg.conf I rapidly develop corrupted fonts in exactly the way it is described above.

I played with various combinations described above to fix this, but nothing worked. I have the same experience with "AccelMethod" "XAA" -- it freezes X completely on the C400 (an i830 chipset), even keys & mouse don't work. But from reading other intel video bugs and some experimentation I found a mix that works. Here's the display section of my current xorg.conf:

Section "Device"
 Identifier "Configured Video Device"
 Driver "intel"
 Option "AccelMethod" "exa"
 Option "MigrationHeuristic" "greedy"
 Option "ExaNoComposite" "false"
EndSection

I've been running with this for several days now, with no font corruption or other video problems. As long as you run kwin with all the compositing effects off, it's great. I get around 230 FPS with glxgears, so not exactly blazing but snappy enough for daily use.
