Help accessing compact flash memory card?

Greetings list. I'm just a user, so I hope this is an appropriate forum
for this question.
Quick summary:
Using a post 2.6.13 kernel, my 16-bit pcmcia compact flash card inserted
via a pcmcia adapter is not usable. My 32-bit wireless network card is
fully usable.
Background:
I have a compact flash memory card for my digital camera that I was able
to successfully access on my computer up until I started using post
2.6.13 kernel. Once I upgraded to a post 2.6.13 kernel, I was no longer
able to access it, at first getting a message along the line of "missing
memory_cs". After digging around the net, I found the "Linux Kernel 2.6
PCMCIA - mini-HOWTO", and I've gone through it several times making some
progress, but I've now reach the point that I'm stumped. I believe the
kernel is setup correctly, as I see the card insert and the pcmcia
subsystem assign it a device.
My best guess as to where my troubles lie is that I'm having an issue
with the user space tools, but I'm at a loss as to how to go about
fixing things. Debian's pcmciautils package uses UDEV rather than
hotplug, neither of which I've gotten my head around. So any hints,
pointers, or words of advice that anyone can provide are greatly
appreciated.
I've provided what I hope are relevant system details below, and I'm
happy to provide any additional information that would be helpful.
Thanks,
- Jeff
