I just released VueScan 6.6 for Windows, Mac OS and Linux.
It can be downloaded from:

What's new in version 6.6
* Significantly improved image cleaning. It now
removes dust spots completely when there's an
infrared channel and reduces film grain at the
same time (with or without the infrared channel).
This is the first version that does a better job removing
dust spots than the ICE algorithm, and even works well
with Kodachrome (ICE doesn't).
