For some quality of patch, yes, but board dies around loading payload, and i did not have enough
time so far to debug, last attempt stuck when coreboot at machine showed me gdb beacon.

I am not sure if all code is correct, and there are few missing parts, ie cas latency is hard
coded to 3, agp is disabled (and i failed to find why i cant change APBASE), also i have weird
problem with reading/writing on this machine with read_config16/write_config16 because they return
incorrect data. I mean register *is* 16bit accessible, (it was DRT iirc), but two 8bit reads glued
with shift and or give other result than 16bit read, but i don't have log with output of 16bit read
on hand right now.
