Hi Ingo,
Me and Masami just discussed this a few emails ago in this thread:)

We're less interested in fpu/sse. The interesting instructions are
those used for page table management, mmio, and real mode execution.
If so, I might find some bugs in x86_emulate.c.

Hi,
Here are the patches of kprobe-based event tracer for x86, version 4.
This version supports only x86(-32/-64) (If someone is interested in
porting this to other architectures, he just needs to port
kprobes/kretprobes and ptrace enhancement[PATCH 2/6]).
I added x86 insn decoder on this
