Are you running -unstable, or 3.3?
Between 3.2 and 3.3, the mmio value got un-traced (with the re-working
of the emulation infrastructure), and I didn't catch it in time. It
should work in -unstable from cs 18749.

What version of Windows are you running? w2k3sp2 has lazy TPR
updates, so it does a big reduction in the amount of TPR writes.
If you want to send me a trace, I can take a look at it and see what I
find as well...
