On further exploration:

Adding "alias eth0 3c59x" or "alias /dev/eth0 3c59x"
or "alias 3c575_cb 3c59x" and then running "depmod -ae"
before inserting the 3c575 card did not help.

Also, I am questioning whether /sbin/hotplug uses
cardmgr to get the modules loaded.  That means that
the messages I sent earlier:

Jan 22 16:43:26 agate /sbin/hotplug: arguments (pci) env 
(PCI_CLASS 000 PCI_ID\x10B7:5157 ACTION­d TERM=dumb HOSTTYPE=i386 
PATH=/bin:/sbin:/usr/sbin:/usr/bin HOME=/ SHELL=/bin/bash DEBUG=yes 
PCI_SUBSYS_ID\x10B7:5B57 OSTYPE=Linux PCI_SLOT_NAME\x01:00.0 SHLVL=1 
_=/usr/bin/env)
Jan 22 16:43:26 agate cardmgr[444]: module 
/lib/modules/2.4.1-pre9/pcmcia/cb_enabler.o not available
Jan 22 16:43:26 agate cardmgr[444]: module 
/lib/modules/2.4.1-pre9/pcmcia/3c575_cb.o not available

may simply show that Card Services is trying to handle the
driver loading, not /sbin/hotplug.

I will have to check and see whether David Brownell is
correct and I am missing the recent hotplug patch sent
by Dan Zink.

Anyhow, if /sbin/hotplug is going to handle the driver
loading using modprobe, than we will probably need a
way to get cardmgr out of the picture.
