[support] Module problems with 6.22?

[Luke]

I just upgraded a 6.20 site to 6.22 via latest drush.

It is worth noting that the 6.20 version of the site, reported all modules 
up to date when I did so.

Once finished, drush told me that it had disabled the following modules, 
because they were incompatible with my version of Drupal:

taxonomy_menu
taxonomy_menu_hierarchy
taxonomy_menu_path_custom
taxonomy_menu_vocabulary_path
admin_menu

What's going on here?

I have re-downloaded these modules at their most recent versions, and 
re-enabled them (except for admin_menu, which I took to latest dev). 
Should I expect problems?
