SRAM and MTD

[Felix Frey]

Hi

I'd like to connect a 32kx8 static RAM (battery buffered) to the ISAbus of my 
x86 based system to frequently store sensitive data which _must_ survive a 
powerfail. Access should be made through the mtd character device. By diving 
a bit into the code I saw there is a ram chip driver, however, I got pretty 
confused. 
Do I have to write my own mapping driver or how can I tell the chip driver 
where it finds my RAM device and how large it is ?
Does the ram chip driver accept any parameters ?

Any help is greatly appreciated.
