For what its worth, on my Winbook J4, I had similar problems, and it seemed to
be related to the order the drivers are loaded or the ports loaded (problem was
if the wireless driver was loaded before the pcmcia drivers). If I wrote an
init script that ran before network/pcmcia scripts, and did a modprobe in the
following order:


Obviously for your system you will have to adjust to your local laptop
(yenta_socket is the basic pcmcia controller, orinoco_pci is my wireless card,
and 8139too is my ethernet).

I also needed to exclude IRQ 9 in /etc/pcmcia/config.opts to get ACPI to work,
and the following declarations that I initially used for a Toshiba Tecra, but
evidently I still need with the J4:

        include port 0x100-0x4ff
        include memory 0xc0000-0xfffff
        include memory 0xa0000000-0xa0ffffff, memory 0x60000000-0x60ffffff
