Just a heads-up, that event number could easily change from boot to boot.
You can preserve your sanity by making a udev rule like the following and
put it (or a symlink) in "/etc/udev/rules.d/"

KERNEL=="event[0-9]", ATTRS{name}=="cx88 IR *", SYMLINK+="lirc%n"

I *think* that rule should work for you Hauppauge card, but I'm making an
educated guess on the 'ATTRS{name}=="cx88 IR *"' bit.

You can confirm/correct the rule by running the following as root:
% udevinfo -a -p `udevinfo -q path -n /dev/input/event1`
where event1 is the lirc dev you want. Hopefully the appropriate match
rule is self-explanatory. '*' behaves as a shell-like wildcard.

my udev-fu is very weak, but the %n substitutes the kernel supplied
number. in which case you'll get lirc[0-9] depending on which event it
matches. If you only have one ir port that you care about, then you'd
probably always want it to be the *same* symlink regardless of which
event it gets assigned to:

KERNEL=="event[0-9]", ATTRS{name}=="cx88 IR *", SYMLINK+="lirc0"

Argh, you're right. That's a better way to go.

If there is more than one card that could match the ATTRS{name} field, the
OP could add another criteria that matches on the PCI slot number (so two
cards don't fight for the "lirc0" name):

KERNEL=="event[0-9]", ATTRS{name}=="cx88 IR *", KERNELS=="0000:01:09.2", SYMLINK+="lirc0"
