Believe it or not, that (export SANE_DEBUG_PLUSTEK) doesn't do a thing!
Absolutely nothing sane related shows up in the log.

That, clipped to a cli, would appear to be working, the scanner is
actually in motion. But it finished very very quickly once the
lamp warmup timeout had elapsed. Looks like 33 seconds overall
elapsed time, and the image.pnm file is a hair over 111k.
Humm, I wonder if up2date ignored me again, and installed new rpms.
If thats the case, thats the end of that program on my system, its
happened at least twice before. Mmm, no, no sane here according to
rpm -qa|grep sane
Ok, scanimage seems to sort of work, why not xsane?
