I think they would probably have been moved into a bitfield setting I think its called "options" in the user table.
You can view the list of bitfield settings by looking in the /includes/xml/bitfield_vbulletin.xml file. I think vBulletin still uses the same name so try doing a "Find" in that file and you should find the info you need.
