As far as memory devices go, detecting is a big part of the entire
process. I also had lots of weird trouble getting this memory card up, I
finally did it but it was quite trying.

On all the memory cards I've seen the CIS is stored on the flash itself,
so if you erase the CIS then it's gone. One of our systems here boots
from a PCMCIA memory card, putting a CIS in there gets in the way. So for
most of my purposes the current driver doesn't work.
