Only cosmetic issue I noticed is that Snow Leopard recognizes my CPU as 2.2GHz when it should be 2.4GHz. I am guessing this may be due to the DSDT. I'll get around to creating my own eventually, but this is good for now. I may try removing the 2 kexts as well to get USB 2.0 speeds, but may wait on that for now.
This probably has to do with the speed stepping of the CPU. It is done by VoodooPower.kext.
