2.5.20 - Xircom PCI Cardbus doesn't work

[Alessandro Suardi]

In 2.5.19 I got an oops on boot (kindly fixed by Peter's patch),
  in 2.5.20 no oopsen but eth0 isn't seen anymore by the kernel:

Note that cb_enabler and xircom_cb are aliased to 'off' in
  /etc/modules.conf since both are actually built in-kernel.

...back to 2.5.18 for the moment.

Thanks & ciao,
