Does this work for you with 4G of RAM?
My boards don't support that much.. :-( Have to try on the AMD boards some time. But I guess if the chipset supports more than 4G you'd have to put the high_table_base to the top of low memory (default would be below 3G I guess) There's no structural problem that would disallow using the mechanism with any amount of RAM.
I don't have a Kontron board, but I copied the implementation to the amdk8 northbridge code. It works for me when I have the RAM "boosted" and it works when I boot with less than 4G, but if I boot with 4G it tries to put the high tables in the PCI decode space since they overlap.
Besides that the patch is working well for me, and I'd like to see it merged.
If it works in the 4G case and I just didn't implement it right for K8:
