I've found some time to post some extra reviews on my blog:

Still to come is the FA18-35/4-5.6.
I don't think there is need to review more common lenses like the DA16-45, DA50-200. I will also copy my comment in this forum lens review database when I finished my blog.
When I buy a new Pentax camera, I maybe redo the test to compare the results. The K-X performance looks really great, but I hope Pentax would make a version with focus indication and with a battery-grip.
