# grep -i serial /boot/config-2.6.31-2.fc12.i686.PAE |grep '=y'
CONFIG_LIRC_SERIAL_TRANSMITTER=y
CONFIG_SERIAL_NONSTANDARD=y
CONFIG_SERIAL_8250=y

So you're missing at least:

CONFIG_SERIAL_8250=y
CONFIG_SERIAL_8250_CONSOLE=y
CONFIG_SERIAL_CORE=y
CONFIG_SERIAL_CORE_CONSOLE=y
CONFIG_USB_SERIAL_GENERIC=y
