It seems that you can't get the irq for the driver module. Either you
don't have enough irqs left, or there is another driver on irq 9 that
doesn't like to share. You should try to configure the
/etc/pcmcia/config.opts so that you exclude irq 9 and see what
happens. If you don't have enough irqs left, you can start the pcmcia
controller in polling mode instead of using an irq of its own. This
should be mentioned in the PCMCIA-HOWTO document. I am not sitting at
my linux notebook right now, or would send you my config files.

If the above doesn`t work, it could be a timing problem. You should
read PCMCIA-HOWTO to work those out.
