To some extent that's true but just turning full preemption including
kernel side with all the associated debug bits and lockdep should make a
whole bunch of things show up even with ordinary workloads.

For 440 tend to boot an ubuntu distro off NFS root with all X & DRI 3D
etc... and then run compiz :-)
