I want to thank you for your DSDT but I still wish it had PS/2 support...

I managed to add it myself but scroll doesn't work... need some help here

Is it because I changed LPCB id from 3A18 to 27B9 to reflect ICH7M instead of ICH10 ?

I could identify some of your mods but certainly not all of them, would you mind listing all the mods you made, in detail ?
