I would be happy to try to reproduce this and provide the necessary
trace/debug info, however I admit at this point I'm not sure which set
of kernel configuration and/or setup is causing the issue.

As I said in a previous message, I solved the jerkiness by using
moused and pointing xorg.conf to /dev/sysmouse. Shall I try with
/dev/psm0 instead and provide the schedgraph info? Or is enabling
PREEMPTION (which I have done in my custom kernel) already "fixing"
this for me, and therefore should I use a GENERIC kernel, just
substituting SCHED_4BSD with SCHED_ULE?
