you use old version of sane. remove redhat version of sane-backend:

rpm -e --force --nodeps sane-backend

and re-install sane:

./configure --prefix=/usr --sysconfdir=/etc
make
make install

see below for more comments

yes 4x20 uses BGR color, fixed in current cvs version.

yes, currently backend uses the capabilites of the M3091 as default. if 
you want to update code to use vpd instead, that would be good.

yes, also because of incorrect defaults.

incorrect defaults i think. though from the interface manual of the 
scanner, fi-4x20 does not support setting the paper size. must be set to 
0xC0. would have to use --paperheight and --paperwidth inside the backend 
to fake paper size setting?

cannot be used in sane. there is no portion of the sane api for accessing 
status of control panel. i have used an external program.
