It's been renamed to "How do I add my journal to my IM profile?" which still contains IM but doesn't contain a specific product name. Probably the best compromise.
Moved it to the "Working with Other Sites" category (all the way at the end) as the first FAQ in that category.
Put in a bit more clearly-worded "LJ Support won't help you with this" and set apart the embedding section with a header, to emphasize the first section in itself.
