Many thanks to the people who responded to my question on how to
access physical memory, but none of those ideas will work.  I am 
trying to write something at the driver level and thus, shared memory
won't work and I'm real leary about openning up kernel memory to just
anything.  There IS a way to do this via normal system/kernel code.  The
console driver has no problem -- I'd like to eventually have a console
driver which supports bitmapped graphics via just an extension of the
escape codes.  (Of course this requires console source.... )

Anyone know how to get hold of physical memory in a driver?  (I/O 
physical memory NOT created by a kernel malloc().)
