Hi Dan,
what is the reason to include the CIS parsing into HAL? Wouldn't it be
easier to ask cardctl to give us these values? We may also plug into
the /etc/pcmcia/ directory (like the hal helpers living in 
/etc/hotplug.d/ and /etc/dev.d/)and send events from there to the hal
daemon?

Would that work? What do you think?

Thanks,
Kay
