Matrix Inverses

I've pieced through some Linear Algebra books and have come up with two differnt ways of computing the inverse of a square matrix. Neither of them seem to be good candidates for real-time graphics. Does anyone have a good bit of matrix inversion code?

I use inverse matrices for fast pre-transformation lighting and poly culling. This way, I can cull and light polys before transforming them to world or camera coordinates.

VTune is cool, I won a copy of it at the XGDC and I must say, knowing what's included with it now, I'd buy it. =)

You get the Intel ICL C++ optimizing compiler plugins for VC++, interactive assembly tutorials, almost all of their docs in *.pdf format, a profiler and bounds checker, and a lot of other things. I'm impressed.
