Not in 2.[123].x. CONFIG_SERIAL_ECHO is long gone and there is no need
to hack the code any more. Under config for char devices, select
"Standard/generic (dumb) serial support" and "Support for console on
serial port". I have only used it with serial support builtin, I have
no idea if it works with serial as a module. In lilo or other boot
loader, pass the console parameter to set com port, speed etc. Mine
looks like this.

image=/test_kernel/2.2.10
label=2.2.10
optional
image=/test_kernel/2.2.10
label=2.2.10-ser
optional
append="console=ttyS1,115200"

Also see Documentation/serial-console.txt.
