PCMCIA not working on hp dv4000

[Paul Webster]

I have now been through the process of upgrading to a 2.6.13.3 kernel,
yenta-socket, and pcmciautils-010. The PC Card slot on my notebook has
been successfully tested with a CF Card PCMCIA Adapter and a 3Com
network card (insert, identification and module loading only, I forgot
to bring home the dongle). Both cards create a
/sys/bus/pcmcia/devices/0.0, but there is no love from the "built-in
passive PC Card adapter". I tried both a Memory Stick and an SD card,
to exercise the different PCI devices found, to no avail. Zero
response.

Any suggestions would be helpful, including hints on how to get
started writing a driver from a chips documentation.

TIA
