To follow up on my own post, I grabbed pcmcia-cs 3.1.5, and compiled it against the 2.2.13 kernel with the following options:

 fulcrum:/usr/src/pcmcia-cs$ cat config.out
 #

After making, the ethernet port worked fine. I think that the key setting is to disable CONFIG_PNP_BIOS during pcmcia-cs's make config.

The modem still does not work upon insertion and/or powerup, but I've worked around this problem by setting the serial_cs driver briefly to polled mode (setserial /dev/modem irq 0) then back to its assigned interrupt. I had to slightly hack /etc/pcmcia/serial to automate this.

The card itself does not revive properly from a suspend, but apmd can be used to electronically eject the card immediately before suspend. The card is automatically reconized when returning from suspend mode. Good enough for me.
