OK, this works, but as the same IDs need the FN key hacks I or'ed the FN
and mouse quirk flags. Also I added the appleir (builtin infrared on the
macbook/pro) to the list of ignored IDs. Therefore the patch though very
similar is again slightly different.

But hey, it worked for me over the last hour on this mbp :-))
Please comment/apply.
