Not if you really aren't copying the stuff to RAM.  Rememer its not
ROM you are looking at but the ROM shadowed into RAM.  So its possible
that you are checksuming the contents of RAM that has not be
initialized.  That would produce the results you see.

Have you looked at the area in RAM where this stuff is supposed to be?

I'm not near a machine that I can look up the command line but use
'hd' to look at the contents of /dev/ram starting at 0x0c0000 and see
if the next 64k are really what you think they should be.    You could
also might use 'dd' and then 'diff' it against your vbios image.
