What was the version of the kernel that supported the card?

Bad news - that driver (renamed to pcmciamtd) is considered broken in
the recent kernels.  However, it may happen that your card is actually
detected incorrectly.  Digital cameras normally use CompactFlash cards
with IDE interface.

Since you are getting messages about memory_cs, I guess you are still
using pcmcia-cs utilities and the compatibility PCMCIA layer in the
kernel.  It should be OK for now.  You can switch to the new interface
once you resolve this problem.

Please run "cardctl ident" and post the output.  Also, it's better to
use dmesg to get the kernel log, since syslog may be omitting some
kernel messages.
