I can't help with your original problem but some comments about this:

That's the SCSI generic buffer size and increasing it may help in some
cases for SCSI scanners. I'm not sure if it does work for these
SCSI-over-parport scanners at all, however.

Anyway, you don't need to reboot. Something like
"SANE_SG_BUFFERSIZE=somevalue scanimage --someoption" will be ok.
