It looks like you got it exactly right. I noticed when xscanimage starts
it outputs a firmware of 1.20. I added this in do_dummy_scan and it looks
like it works perfectly! Thanks!

[Actually, it looks like do_dummy_scan returns SANE_STATUS_GOOD if
it doesn't know about the scanner, I'm kinda curious why it doesn't at least
return something to indicate that something is wrong. Is that an idea for
a future improvement?]

Here's the patch, which includes the x6el patch posted by Christian Grigis
on 30-Nov-1998.
