You need to enable the VT console in the kernel config,

CONFIG_VT_CONSOLE=y
CONFIG_VT_CONSOLE_SLEEP=y

In specific, for hammerhead config,

% grep "CONSOLE" cyanogenmod_hammerhead_defconfig | grep '^CONFIG.*'
CONFIG_CONSOLE_TRANSLATIONS=y
CONFIG_VT_CONSOLE=y
CONFIG_VT_CONSOLE_SLEEP=y
CONFIG_HW_CONSOLE=y
CONFIG_SERIAL_CORE_CONSOLE=y
CONFIG_SERIAL_MSM_HSL_CONSOLE=y
CONFIG_DUMMY_CONSOLE=y
CONFIG_ANDROID_RAM_CONSOLE=y

You will also need to change the BoardConfig.mk for your device to have,

console=tty0 instead of console=ttySAC2,115200 in the device tree, see 
patch to hammerhead device tree.
