This patch disables the AC97 modem via the ICH4 LPC disable function register early in the boot process. Leaving it enabled was causing resource allocation problems, making IO read/writes under 0x200 fail. As I found out by trail and error it has to be done right after the LAN Enable gpio pin is driven high.
