This was with the old driver and i still had problems.
But, the thing i changed was in include/linux/mtd/doc2000.h

In that file there is a few defines for ReadDOC and WriteDOC i just
commented out the first two cases of those and kept the last one with readb
and writeb.

I remeber there was something odd going on tho, the module wasn't always
loading and i think i had to load docprobe too.
I think it had something to do with the probing of the chip, it wasn't
always able to bring the chip out of reset mode.

The doc chip have a tendency to enter reset mode, i had a test program to
dump memory but this didn't return anything usefull since simply reading
from the memory where the doc chip is makes it enter reset mode.

I also thing i changed the address where it probed for the doc chip, i think
this was in docprobe or something like that.


Anyway, this is all from memory and it was a long time since i experimented
with it, so i may have remeberd some things wrong.
