pccardd forces irq 9 on pcmcia modem

Hello,

I'm having trouble with a pcmcia modem. It is actually detected and set up as 
a "generic serial" but it runs very slowly. I should be able to get about 
3.4k/s but can only get about 1k/s. I had the same trouble with Linux but was 
able to fix it; I found that the irq was being set to 0 and setting it to 3 
made everything run perfectly. Under FreeBSD, I tried setting up 
/etc/pccard.conf as follows but it still forces it to irq 9:

irq 3
card "HONDA ELECTRON CO.,LTD" "AH-H401C"
	config 0x9 "sio" 3

As you can see from the output of dmesg below, there is no other device on irq 
3. I also have another (lesser) problem; no pccardd entries appear in 
/var/log/messages. If I run pccardd -d, they all show up fine on the console. 
I tried uncommenting the "*.* /var/log/all.log" line in /etc/syslog.conf, but 
they don't show up there either.

The output of pccardc dumpcis is as follows:
