No.  This is _not_ what is called a cell.  "Cell" is a Forth concept.
A cell can be any size.  Open Firmware puts the extra restriction on it
to be _at least_ 32 bits.

The thing you are referring to is what is called in OF

	"32-bit integer property encoding format".

It is defined to always be 32-bit, and not the cell size of the 
firmware,
so that you can use a 64-bit firmware with a 32-bit OS, and vice versa
(of course there could be different reasons why this isn't practical, 
but
that's not the point).

In OF words, this format is normally abbreviated as "int".

Btw -- beware of the fact that such an "int" does _not_ have any
alignment restrictions -- so you better read it byte by byte...
