[3.5] Crit where it counts

[The Glyphstone]

How many different ways exist in 3.5 to bypass or ignore immunities to critical hits? I can think of:

-the Golemstrike/Gravestrike/Vinestrike line for their respective creature types.
-Swift Hunter for a Ranger/Scout's Favored Enemy.
-the Epic Mace of Ruin for objects and constructs.

[Thrice Dead Cat]

True Death Crystals, Greater (MiC 66) allow for sneak attacks and critical hits on undead. Demolition Crystals, Greater due the same for constructs.
