That looks like a good idea; it can be implemented easily and nicely
within Linux. And for transparency we should. What will stay different
is the naming convention of Linux partitions.
The environment is allocated in ``Firmware Temporary'' memory, isn't it?
We don't free that yet but we should, for low memory configurations that
should be a significant amount of memory.
