Hiding a Calendar's Entries from Homescreen on a Today Theme

So I've just upgraded to .419, which is sweet but now I'm having an issue that I didn't with .230.

I like the fact that Facebook can put entries into my calendar to remind me when my friends' birthdays are. BUT I don't want those entries showing up on my home screen with today themes. Somehow this was possible with .230 as I would get a reminder on the day of a friend's birthday but it would never show on the home.

Is this still possible with .419? If so, any ideas how I can do it?
