There is a (compile time) option to the /boot code to print the memory sizes
it finds from the BIOS, there is also some old code (IIRC just compiled out)
that uses some alternate schemes (which don't work on new systems) to find
the size and ranges of available memory.  The info is then passed to the kernel.
Possibly the bios is getting this info wrong!
