I am curious, why does the patch != the mem=8832M?
I'm not sure... can you post your e820 map from boot and the contents
of /proc/mtrr? Maybe my patch is trimming off a few too many pages, or
maybe 8832M isn't quite right and actually ends up leaving you with a
few uncached pages.

I cannot post the E820 memory map, I have no way to capture it, I cannot
get anything from netconsole and dmesg does not show it either.

But that still works.
