Canoscan hell on Mac OSX

With a clean OSX on hand, I need to reinstall most of the hardware driver, including the driver for my old school Canon Sacnner N670U.  However, I found out the the lastet driver for CanoScan LIde25 DOES not work well with my scanner.  Errr actully, may be it's just the Canoscan toolbox that was failing. 

Here's what I know for sure, that Canoscan toolbox 4.9.3.47 DOES NOT work.  The Canoscan 4.1.3.0 works great though, which I think it the "CanoScan Toolbox Inst Carbon E" file.  And then for the driver it needs to be ScanGear CS 7.0x.  So maybe I'll give "lide25osx11031en.dmg" a try first, and if failed I can try "lide20lide30n670un676un1240uosx7011aen.dmg".  Based on the file name, I found the later one sounded more promising.
