Well, you're closer anyway. :)

Same as mine, I have a Umax Astra 1200S.

At least we're talking to the card now.

Hmm...sounds like the card, or at least the driver, can't see the
scanner for some reason.  When the SCSI bus is being probed at boot
time, does the SCSI card report finding the scanner?

If it its finding the scanner at boot time, try doing a "cat
/proc/scsi/aic7xxx/0" (or similar) and see if it lists the scanner under
Device Information.

If it is listed, you might try unloading the adaptec driver by doing an
"rmmod aic7xxx", and then reloading it with modprobe (leave sg loaded). 
Though, I would think that the moment you loaded sg.o that it would see
the scanner and report it as a usable device, but try that just in case.

That's actually a very old version of SANE (as in years), and probably
wouldn't work with your scanner anyway.  I didn't notice the first time,
sorry.  You can get the latest version of SANE from
http://www.mostang.com/sane/, they have it available in RPM format.

Try the above first.

I'm sure that it's something minor keeping things from working.  Once
that's taken care of everything should work fine.
