I'll be the first to point out that I know very little about how
the NCR driver works.  The main point of my porting it to CAM was
to get the driver far enough along to where Stefan can polish it
up.  I don't know how any of my changes could make it so the second
NCR card is no longer probed (I didn't touch the probe code).

It seems that I broke outgoing messages for the 810.  It could very
well be that I broke some alignment constraint for one of the data
structures that only affects the 810.  The interaction between the
script and objects in kernel memory is not explicitly documented
with the data structures so this wouldn't surprise me at all.
