It should work for quertet.

I compare the schematic of S4880 and quartet, and the SPD_ROM access part is
the same.

You need to update raminit.h and amd8111_early_sumbus.c too.

Tried this, doesn't work. I end up with 0KB memory detected on each 
CPU. Is it only my Quartets that behave like this?

Aaah. I found the culprit. All SMBus addresses have to be shifted right
by one compared to what the data sheet says. I forgot to do this for the 
DIMM modules.

I checked your changes to amd8111_early_smbus.c into the freebios2 tree.
I still can't see the onboard network adapter, even with only 3G in the
machine. So I'll try the PCI-X master changes here as well.

Thanks a lot, Yinghai!
