Seems to be unused.

ich9 DSDT changes:

     Scope (_SB.PCI0)
     {
         Device (ISA)
         {
             Name (_ADR, 0x001F0000)  // _ADR: Address
             OperationRegion (PIRQ, PCI_Config, 0x60, 0x0C)
-            OperationRegion (LPCD, PCI_Config, 0x80, 0x02)
-            Field (LPCD, AnyAcc, NoLock, Preserve)
-            {
-                COMA,   3,
-                    ,   1,
-                COMB,   3,
-                Offset (0x01),
-                LPTD,   2
