Very cool! Did you hardcode the amount of memory or do you probe it from
the emulator?

Yes. Most likely other parts of the device tree are missing as well.

there's 

.properties  to show device properties and
ls           to show sub device nodes  and
words        to show methods defined for the current node.

Maybe an unintended one ;) But not a natural limitation. How do you
create the node?
