Hi Martin, I added back that function and tried changing / adding some other stuff and guess what? Serial console works! Thank you for pointing in the right direction.
Now the next problem: this motherboard uses an Intel X4X northbridge with DDR3 RAM. This is the serial console output: ======================================================================= Setting up RAM controller.

Should I start a new thread about DDR3 support for the Intel G41 northbridge?
