Yes, I tried to ingore it because you initially said that it was a
Xsane problem, but Oliver pointed out some strange code in my
code :-)

Actually, I cleaned up the EPSON backend as well, the previews do work
now. So far the new code is only available through CVS, but give me
a few more hours and you will be able to download it from my site.

This is odd. I just tested this with my Expression1680, and it works. The
Perfection 1640 has a firmware bug, it delivers the three color channels
in the wrong order. I am correcting for this in the backend, but this
should not create the black line.
Can you send me a scan in preview resolution (probably 50 or 75 dpi) that
shows this problem? Please either email it to me, or make it available
on the Internet so that I can download it.

I am not familiar with "Kleo", but I am pretty sure you will not be able
to use it under Linux. I have a ColorMouse Too! from Color Savvy, which of
course does not have a Linux driver either, but it has a serial interface,
so I can run the software under vmware. Unfortunately it does not work
with Wine. The USB interface of the Kleo device makes the vmware solution
impossible, so you have to boot into Windows when you want to use the
colorimeter.
You don't need a colorimeter if you just want to calibrate your scanner. A
IT8 target and the Scarse software is all you need (http://www.scarse.coloraid.de).
You can get a relatively cheap target from http://www.targets.coloraid.de.
