I thought we had Canonicity safely shipped off to Mordor. With her gone, there's naught to worry about.
On a more serious (and slightly more related) note... there were eight palantirs!?! Are you sure? I always thought... "seven stars, seven stones, one white tree". Did I miss out on something?
And speaking of numbers... is there a biblical importance for "9"? We've got our holy trinity of elven rings, our perfect number of dwarven rings, our ultimate power source of one ring... and then nine. Interesting though, that the "holy trinity" bit goes to the Elves, who are more spiritual beings than Man. The "perfect number" goes to the perfectionists that are dwarves, and the "one" is for the one force that can make or break existance in Middle Earth.
