Sure, can you find the assembly code that does serial init?  Possibly
it's not all in once place but rather scattered out in a few places,
meaning that it's simpler to look at documentation than code.

Geode documentation is available but I suppose time is scarce.

I'm afraid it isn't relevant. He is refering to BIOS interrupt
services which coreboot doesn't do at all and which are unrelated
to the hardware interrupts that are missing in your system.

Please see http://en.wikipedia.org/wiki/Interrupt and
http://en.wikipedia.org/wiki/BIOS_interrupt_call for more info.
