Like this ? E.g. this is what I found for ICH5's LPC_EN, offset address
0xe6:

00:1f.0 ISA bridge [0601]: Intel Corporation 82801EB/ER (ICH5/ICH5R) LPC
Interface Bridge [8086:24d0] (rev 02):
// snip
e0: 00 00 00 80 00 00 08 14 33 22 11 00 00 00 67 45

pci_write_config16(PCI_ADDR(0, 0x1f, 0, 0xe6), 0x1408);

Attached the mainboard code as well.
