That's pretty common. BIOS tables etc are seldom page-aligned, and
afaik we handle it all correctly. Look for PFN_UP(start) and
PFN_DOWN(start+length) patterns in both e820.c and memblock.c.

Sure, it is _possible_ that we have some place we screw up in, but I
think it's unlikely. As mentioned, non-page-aligned memory is quite
common, especially in the low BIOS region just under the 640kB mark.
