[PATCH] pcmcia: request CIS via firmware interface
Use the firmware method to load replacement CIS tables. It is recommended
that the /lib/firmware/cis/ points to /etc/pcmcia/cis or the other way round
so that both old-style cardmgr and new-style hotplug/firmware can access these
"overwrite" files

+ Some PCMCIA cards require an updated Card Information Structure (CIS)
+ to be loaded from userspace to work correctly. If you say Y here,
+ and your userspace is arranged correctly, this will be loaded
