Yes, and the 'Address Range Descriptors' said the same thing. However, I
think the problem is that you ran grub from the command line. If you did,
displaymem just lies to you (making it completely pointless!). To get the
right info you have to break to the command line at the grub boot menu (by
pressing 'c') and type the command there. And then write down the output
since you won't be able to cut-and-paste. :-)
