Anderson Lizardo,
Unless I misunderstood; if the package itself has a /opt path in it
the maemo-optify won't run on it. So if you are "installing" anything
(even one file) under the /opt path (which based on what I see you saying
below it appears you are); it should cause the maemo-optify to not run.

No, because the optification was done by creating a "pymaemo-optify"
package which bind mounts the relevant Python directories from /usr/... to
/opt/pymaemo. These mounts are done during device boot by
/etc/init.d/pymaemo-optify (they are not mounted inside scratchbox, of
course).
This means that there is no change required for python packages to become
optified, they just need to depend on python.

Actually the list of directories handled by pymaemo-optify is variable (but
not expected to change). They are defined in /etc/default/pymaemo-optify and
currently is:
/usr/lib/python2.5
/usr/share/pyshared
/usr/lib/pyshared
/usr/share/python-support
/usr/lib/python-support
One idea might be to check whether this file exists and ignore any packages
which install files to the directories listed on the "BIND_MOUNTS" directory
(note that this file is a snippet of shell script read by
/etc/init.d/pymaemo-optify).
Or you can hard code this list somewhere, and you will get at least most
Python packages ignored. As with every heuristics, we can't get 100% of
cases, and others will need to have to be manually opted-out.
My two cents,
