What you actually want to do is to instruct modprobe to pass a certain
option when the module is loaded. While you can certainly do that via
udev rules it's more of a hack than anything else.

The modprobe variant shipped with Linux 2.6 systems (i.e. from
module-init-tools) expects its configuration in /etc/modprobe.conf
or in separate files in /etc/modprobe.d/.

So, try something along the lines of "mkdir -p /etc/modprobe.d && echo
'options hostap_cs ignore_cis_vcc=1' >> /etc/modprobe.d/hostap_cs.conf".

The reason why this isn't enabled by default is that it bypasses a check
that tries to avoid voltage mismatches between the pcmcia/cf card and
the slot. You can use it at your own risk but I'm still waiting for
someone with knowledge of the hardware to confirm that it can't lead
to 5V being applied to a 3.3V card.
