I believe Favor of Illmater is from Magic of Faerun and is one of the spells they renamed in the spell compendium (the formentioned Favor of the Martyr).
Healing lorecall from the spell compendium can remove daze, but requires the help of another party member. Still a useful trick for a cleric helping out a mage's greater celerity tricks.
There is also a template, Fire souled, from dragon magazine that grants immunity to daze. It is listed in the template index on crystal keep, but the LA is +3, not the listed +1.
