I added these two sections to /etc/pcmcia/config:

device "realtek_cb"
  class "network" module "cb_enabler", "realtek_cb"

card "CardBus PC Card"
  manfid 0x0000, 0x021b
  bind "realtek_cb"

Why? I'm pretty sure that all PCMCIA/Cardbus stuff is disbled in the
kernel .config-file. But the driver and the kernel was built on another
machine, maybe I did something wrong.

I can not use the kernel driver, since the Cardbus driver in the 2.4
kernel does not support the old Cardbus bridge in my notebook. It uses
ISA IRQs, and only the Cardbus driver from pcmcia-cs has a fallback to
ISA IRQs implemented.

Thanks, I will look at it.
