How did you backup and restore the files?  If using pax, tar or rsync
there are options to preserve file modes/permission bits, ownership etc.
For instance, tar when creating an archive will store that information
by default, but at extraction the -p flag must be supplied to apply
archive-stored permissions to the extracted files.

You also have to make sure that your group and user IDs correspond to
those on the old system (/etc/group and vipw to edit /etc/*passwd*).

The mtree files are indeed also supposed to hold the default file
permissions, and I think that it can run through files and restore
permissions, however I have no experience with it personally.
