You posted 'fs objects = acl_xattr' was this a typo? also do you have
the 'attr' package installed.
A quick test by creating a test dir by root and adding a users ACL with
setfacl and then changing the owner and group via chmod & chgrp never
touched the ACL.
I would also like to point out that changing /etc/fstab is no longer
required on Debian & Ubuntu if you use ext4 (hint, hint Marc ;-) )
Having said all that, why are you altering the ownership of the
directories and files on Linux, set them (as per the wiki) once on
linux, then set or change them from a windows client.
If you don't have any windows clients, learn how to use setfacl.
