 but still category and tags pages return 404. Please note that Advanced
 Permalinks plugin (known to cause issues with WP 3.1) was in use when it
 was upgraded, so it might have to do something with that. Its disabled at
 the moment.

 I've just tried it with /%postname%/ permalink and 'cat' as category base.
 It is working for me.

 Permalinks are broken only if I use that "Advanced Permalinks" plugin.
 After disabling it did you flush rewrite rules?
