The `systems base address, i.e. where the RAM begins', I suppose it's the one
from the tablet, not the pc.  If so, the command

 $ extract-ikconfig zImage | grep PHYS_OFFSET

should be given from within the tablet.  Then that script should be copied on
the SDcard and be run from there after mounting it.  I tried, but it says `not
found'.  As suggested in the tutorial, I also looked for "System RAM" in
/proc/iomem on the tablet.  There are two occurrences:

 80000000-bbffffff : System RAM

and

 bd800000-becfffff : System RAM

.  Or maybe the system base address is the one of the computer?  Run that
script in the PC, it produces:

 Usage: extract-ikconfig <kernel-image>

.  So I'm stuck now.  Please help.

Thanks,
