Chipset limitation. It uses up most of the MMIO region above 3GB
preventing RAM from being mapped there, and doesn't support remapping
the covered RAM to above 4GB. Nothing the kernel can do about it.
Well, I guess I learned the hard way. So it's better not to buy 4GB
... it turns out to be the same as buying one with just 3GB RAM.
Thanks,
Jeff.
