I solved the usb problem using USB kexts from 10.6.2 but when connecting some usb device like a pendrive, in a while the whole system lags.

There is a report log

08-12-10 16:33:02 kernel IOHIDSystem::relativePointerEventGated: Unwanted Direction Change Y: oldDy=1 dy=-9
08-12-10 16:33:03 kernel IOHIDSystem::relativePointerEventGated: Unwanted Direction Change X: oldDx=-2 dx=2
08-12-10 16:33:03 kernel IOHIDSystem::relativePointerEventGated: Unwanted Direction Change Y: oldDy=-4 dy=7
08-12-10 16:33:05 kernel IOHIDSystem::relativePointerEventGated: Unwanted Direction Change Y: oldDy=4 dy=-1
08-12-10 16:33:08 kernel IOHIDSystem::relativePointerEventGated: Unwanted Direction Change Y: oldDy=-8 dy=54
08-12-10 16:33:09 kernel IOHIDSystem::relativePointerEventGated: Unwanted Direction Change Y: oldDy=-3 dy=5

And continues until I reset

Also my CPU is recognized as a 2.6GHZ Core Duo, and I overclocked that to 3.01 (I'm using Chameleon RC5)
Sorry for my bad english xD
I SOLVED I MY PROBLEMS WITH THE USB

Just using the kexts from multibeast and for the cpu using legacy_kernel v2 and boot.zip xDDD
The cpu was a TSC problem
