The vBulletin 3.5 product system does handle settings that are attached to products.
However, if you already have the settings from the 3.0 Version in your database, you will run into problems.

Running this query before installing the product XML should take care of this:
[sql]
UPDATE setting SET product='aws', volatile=1 WHERE varname IN ('warn_version', 'warn_hierarchical', 'warn_automatic', 'warn_automaticpm', 'warn_autocomments', 'warn_automatic_warner', 'warn_warner', 'warn_collector', 'warn_banned_limit', 'warn_points_before_banned', 'warn_warnings_before_banned', 'warn_banned_usergroup_id', 'warn_protected_usergroups', 'warn_troll_usergroup_id', 'warn_restore_groupid', 'warn_incr_ban_days', 'warn_max_no_bans', 'warn_bans_mature', 'warn_viewoption', 'warn_multiple_per_post', 'warn_send_em_warning', 'warn_send_pm_warning', 'warn_email_on_ban', 'warn_historical', 'warn_allowoffpost', 'warn_warnings_per_page', 'warn_textbutoption', 'warn_modoption', 'warn_sig_thresshold', 'warn_avatar_thresshold', 'warn_aprotected_usergroups', 'warn_pmcutoff', 'warn_admingroups', 'warn_smodgroups', 'warn_modgroups', 'warn_savecopy', 'warn_savecopyforum', 'warn_allowalerts', 'warn_allowalertscomment', 'warn_alertslifetime', 'warn_savecopyalert', 'warn_includepost', 'warn_allownotes')[/sql]
