PCMCIA on EPIA ITX M12000 problems

[Johan Bilien]

Hi,

I'm trying to get a WLAN PCCard working on my IPX EPIA MII12000 board.
By I'm seeing a number of problems.

First of all I was getting the
kernel: cs: pcmcia_socket0: unable to apply power.
message as soon as I would insert the card. Values returned by lspci
(including the device id) were then completely bogus.

I added override_bios=1 option to the yenta_socket module. After that
the message is gone, but still the values returned by lspci are strange:

0000:02:00.0 0080: 1814:0102

PME(D0-,D1-,D2-,D3hot-,D3cold-)
                Status: D0 PME-Enable- DSel=0 DScale=0 PME-

I know from trying the card in my laptop, where it works fine, that the
real ID is 1814:0302 (one bit difference ...) and that the memory should
be accessible.

The board has a Ricoh bridge:

Let me know if I can provide some more information.
