Death Pact would give mages something other than Man-at-Arms stuff, but I'm never going to put 5 points into Witchcraft when I could just get Willpower and have comeback kid.
I'd rather see a talent that improves summons than one that might save a character once in a blue moon. Summons Gain 2x Leadership bonuses from their master. Or summons have 30% extra health and armor. Whatever to make a summoning focused build possible.
Fashion Plate is good, although I'm not sure if I'd ever have the spare ability points on a mage to take it, and of course mage is the only class I'd take it on.
Graven Importance seems like junk to me, since it only applies to a few effects.
Head Start seems to be a "glass cannon users only" talent, and while almost every build should have glass cannon I'm not sure that's a good thing.
Jailbreaker I think we discussed in the other thread, if there was ever a point to lockpicking it could be a decent talent but that's not currently case.
Mind Over Matter is fine, although the str penalty rules it out for many builds.
Savour the Moment would be a new mandatory cheese talent, for the same reason Walk it Off is terrible, but in reverse of course.
Walking Almanac might as well just be +2 Loremaster, gear identification isn't that big of a deal and this'd just make it more convenient. Identifying enemies is also of questionable value - many have obvious weaknesses/resistances, and the more you've played and know enough about the enemies from experience, the less value it has. I'd give it a little combat bonus to represent better knowledge of weak points or whatever to make it more enticing.
