The application manager should offer the update after a manual refresh (needed so that it will see the packages with the new priority defined by the enabler package). If it doesn't please clear the log, refresh again and post the contents of the log here (or PM me if you prefer).

I had one report where an SD-booted N800 didn't see the update, but the problem turned out to be that the catalogue.tableteer.nokia.com repositories were configured twice and removing the duplicate repositories fixed it. Not sure why that would happen (both copies had the default 500 priority) or if there's anything that can be done about it.
