Hi, thanks for the response.

I've updated the plugin (on GitHub, not yet wordpress.org) to work
with the new API. Yes, much easier :-)  Just a few tweaks and the code
I've got in place for post screen meta boxes works fine for 3.5

I left my old code in for backwards compatibility. I'm checking on the
actual WP version, not on the existence of a hook. Maybe not always
the best way around, but I guess this means now I don't have to worry
about when you re-implement attachment_fields_to_edit for your
backwards compatibility...
