I use an Epson 1640SU too and it works here, but not out of the box.
I use kernel 2.6.6-rc3.  In  sane-backends-1.0.14/backend/epson.c
make the feed() function to immediately return SANE_STATUS_GOOD;

Then use scanimage -d epson:libusb:00x:00x  --source "Automatic Document 
Feeder" ..
and it should work.
