Tried again just now, and now nothing works: not xsane, not scanimage, 
not gscan2pdf.  It started running the scanning head down the page in 
xsane when I selected 16-bit bit depth, but it threw an "invalid 
argument" dialog and the scanning head kept going until it hit the stop 
down by the hinge (at which point I unplugged the cable).

It's looking more like the fault is with the backend driver (genesys, in 
this case), not the applications.
