Yes, I'm aware of corruption resistance, which seems a bit underpowered compared to resist energy, to the tune of half as effective. Also, it's an abjuration, just like resist energy. All of this, however, discounts the fact that corruption resistance is a newer spell, and didn't exist when I was running my 3.5 game. I still like undetectable alignment as a damage resistance-type spell, as well as the vanilla "I'm chaotic evil but you can't tell" use.
