Being picky about case?  Thats how xsane reports it as when bringing 
up in driver selector choice window...

Oh?  Tell that to epson-kowa iscan-1.4.0 people.  It also worked 
just fine with 1.3.0, but 1.3.0 had licensing problems and was 
pulled.  1.4.0 replaces it, just announced a couple of days ago.  
The epson gui frontend 'iscan' for linux won't build now 
(pisa_something-or-other errors the make, like there is a missing 
header file or some such), but the libs are made first, so they are 
built and can be installed.  ??? or were they?  According to my 
reading of the makefile, the executable libs should be in 
/usr/local/libexec, and there are only amanda things there.  
Humm....

In /usr/local/bin, I have a 5 month old iscan, so that didn't build 
this time.  But all the libs are there in /usr/local/lib, dated 
yesterday when I tried to make & install the new iscan-1.4.0.
So I think its safe to assume they are being used since the scanner 
works quite nicely in color modes at least while using the GT-7200 
driver choice.

I've since discovered that gocr was not installed, so I fixed that 
with gocr-3.7, and kooka can rotate the final scan (or at least its 
display thereof).  I scanned the color plate print that came with 
my mobo, and then sic'ed kooka after a 600 dpi image of that to do 
the ocr.  After an hour I see that I have some cpu back (setiathome 
is now running again) but nothing has occured on the screen its 
running on and the kde rolling wheel animation is still going at 
the same old speed.  And half of my 512 megs of memory is now free 
although its still 329 megs into the swap.  So the end of this 
story has yet to be written...
