For VGA support enable:

 CONFIG_VT
 CONFIG_VT_CONSOLE

Then try with (I'm not an expert for x86)
 CONFIG_FB_VGA16
 CONFIG_FB_VESA
 CONFIG_VGA_CONSOLE

For the serial console:

 CONFIG_SERIAL_8250
 CONFIG_SERIAL_8250_CONSOLE
 CONFIG_SERIAL_8250_PNP

Are you using a correct cable (host-to-host)? And don't use spaces in this 
parameter. It must be "console=ttyS0,115200" to keep it as one parameter.

For x86 the net should be full of guides. And you should grep for the 
word "console" in the Linux Documentation/ directory.

Maybe it already boots, but you just don't catch its output. Try harder ;)

Hard to say from here. I haven't an x86 at hand, so I can't do a quick test.
