There is a new version of the microtek2 backend in the CVS-Snapshot
which is available at www.mostang.com/sane. I don't know if it helps but
if you like you can test it.

It depends on the bug in the firmware, i think you will have to find it
out by yourself.

You should modify the backend so that it corrects the values rather than
xsane. Xsane is identical for all scanners, the scanner-dependent code
is in the backend (microtek2.c in your case).
