[OS X 10.8] Super IODevice: [Fatal] found unsupported ship ITE sequence ID=0x8572, Winbond sequence

I have the Asus g75vw too. What do I edit in the dsdt to add fan speed data to HWSensors? Or can I edit the kext itself?

You would have to research the DSDT to find where to read fan speed from. Then add a patch to the DSDT to implement FAN0 method in a device attached to ACPISensors.kext. Refer to the ProBook patches for an example: https://github.com/RehabMan/HP-ProBook-4x30s-DSDT-Patch
