Well, I worked at it later last night, and finally Got It.
For anyone reading this, here's what I had to do to get RH 9 to accept a
PCMCIA-attached cdrom:
0. a) In my laptop's BIOS, I told it to not auto-detect for PCMCIA,
but to use PCIC emulation.
b) $> sudo mkdir /mnt/cdrom
1. The RH install, in spite of detecting pcmcia, defaults it off.
Edit /etc/sysconfig/pcmcia, to "yes". My laptop has an
indsutry-std. Intel, so I added the PCIC. The result looks
like this:
PCMCIA=yes
PCIC=i82365
PCIC_OPTS=
CORE_OPTS=
2. I've got an old EXP CD Traveler 2020. The PCMCIA info
for Linux shows a couple of other EXP cards supported,
including another, older model of Traveler, so
a) Open a second xterm, and do
$> sudo tail -f /var/log/messages
This will let you see new lines appended to the
messages file as they occur. This way, if something
Not Good happens, you'll see.
b) Start PCMCIA:
$> sudo /etc/rc.d/init.d/pcmcia start
c) Enter $> cardctl ident
What I got was
Socket 0:
product info: "EXP", "CD+GAME", "C2"
Socket 1:
no product info available
d) edit /etc/pcmcia/config as necessary. What I did was
to simply copy the entry for the older Traveler,
then change it to match the output from the last
command. That is, here's the original, and the
cloned entry:
card "EXP Traveler 620 CD-ROM"
version "EXP", "CD+GAME", "C1"
bind "ide-cs"
card "EXP Traveler 2020 CD-ROM"
version "EXP", "CD+GAME", "C2"
bind "ide-cs"
e) Since you've done all this editing of config files,
stop PCMCIA services:
$> sudo /etc/rc.d/init.d/pcmcia stop
and then start 'em again:
$> sudo /etc/rc.d/init.d/pcmcia start
At this point, what you should see in the messages is something like this:

Note that it *tells* you what device to refer to; in my case, it's hdc. Hmm,
even as I write this, I just took a look, and the link /dev/cdrom->/dev/hdc
seems to have been automagically added, as did the line in /etc/fstab:
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
We're done. Users can mount CD's too, not just root.
