I tried that sequence of steps...it errored out on both attempts to scan 
(scan and preview).

It's definitely 1.0.25:

salfter at janeway ~ $ emerge -pv sane-backends

These are the packages that would be merged, in order:

Calculating dependencies... done!

I tried nuking ~/.sane and rerunning the steps above...still no joy.

Next step might be to bring the scanner in to work and try it out with 
my old computer that I took into the office.  There, it'd be running on 
Gentoo Linux in a VirtualBox VM under Windows 7. I already have that box 
working with an ancient LiDE 20 that Canon doesn't support under 
anything newer than Windows XP and would just need to compile in the 
genesys backend (the LiDE 20 uses the plustek backend).
