Being new to device driver writing I'd like to obtain 
a few short hints on how to proceed mapping the physical region
of a device into the driver's address space.

Does the isa_device structure do this for me already?

My device has a 16 K block at 0xc8000 (for example) and I want to
read some location to verify that the device is there and second
to download some data into that memory region.
