AGREED. I had a Tamron 10-24mm for my Nikon D60 - HORRIBLE auto-focus and corner sharpness.
If you plan on moving up to the D90, get the Promaster brand 17-50mm f/2.8; it's the EXACT same as the Tamron but without the slow and loud built-in motor. Instead, the Promaster is driven by the camera body's motor which is much better than Tamron's built-in motors. Plus, the Promaster is way cheaper if you can find it at the right place, and comes with life-time warranty.
