To help my understanding, would someone please clarify what David Hinds said
in this email:

Which if I understand correctly is why I have to put an entry in
/etc/pcmcia/config like the following:
card "PRETEC"
  version "PRETEC", " SERIES-2  4MB FLASH CARD"
  bind "pcmciamtd"

but I notice in pcmciamtd.c a bunch of PCMCIA_DEVICE_PROD_ID12(...) calls
are these over riding /etc/pcmcia/config, i.e., do I have to mod pcmciamtd.c
to get it to really be used for the Pretec card?

Clarification desired:
does pcmciamtd replace memory_cs and iflash2_mtd fully, or would I have to
code up a pcmciamtd iflash2 handler? 
I really do not see the documentation on the site or in the code to resolve
this (I have been a simple user of what already worked at an OS level, and
not fully immersed in the MTD physical device and device driver world, so
maybe the docs are there but are hieroglyphics to me).
