I need this a dsdt patch for this motherboard as well. My GA-G31M-ES2L was fried after a power drop, then spike. I "upgraded" to the DG43GT. I can paypal $20 for a successful patch.
***UPDATE****
I have DSDT almost working. HPET patched, no more CPU kernel panics. The only issue I am having is USB. Once the computer wakes from sleep, it forgets all the USB.
attached is current dsdt.dsl
