That's the one

Yes. It's really easy, e.g.:

import sane
sane.init()
scanner = sane.open(sane.get_devices()[0][0])
scanner.source='ADF' #select ADF sheet feeder as source
scanner.resolution = 200	#set resolution in dpi
scanner.mode = 'Color'
img = scanner.scan()
img.show()

As I said, only thing I haven't figured out yet is how to get the second image 
from a Duplex scan (other than by using xsane), everything else works to 
perfection
