I have no idea about the E7210 (or the 875P - I was not aware that they were this closely related), but without checking any docs I'm assuming a 4G memory ceiling and no remapping capability.

I'd appreciate if you could send me both lspci and /proc/iomem output when you get one of these with 4G or more ram installed. Off list, please.
