Physical address

[Die Gestalt]

Hi all,

I would like to know if there are drivers in a vanilla FreeBSD kernel
that write to *physical* memory addresses between 0x1000 and 0x4000.

>From what I inderstand the region between 0x1000 and the first
megabyte is mapped read only, but that doesn't prevent you from
accessing the region if you really want to.

Hope my question makes sense.
