This did not work for me.  I created the following rule and saved it
at /usr/share/hal/fdi/preprobe/20thirdparty/10-ignore-i2c-ir.fdi
<?xml version="1.0" encoding="UTF-8"?>
<deviceinfo version="0.2">
<device>
 <match key="info.product" contains_ncase="i2c ir">
    <merge key="info.ignore" type="bool">true</merge>
 </match>
</device>
</deviceinfo>


I used lshal and it gave me the expected output as detailed in that link:
udi = '/org/freedesktop/Hal/devices/temp/135'
  info.ignore = true  (bool)
  info.parent = '/org/freedesktop/Hal/devices/computer'  (string)
  info.product = 'Ignored Device'  (string)
  info.subsystem = 'input'  (string)
  info.udi = '/org/freedesktop/Hal/devices/ignored-device'  (string)
  input.device = '/dev/input/event7'  (string)
  input.product = 'i2c IR (Hauppauge WinTV PVR-350'  (string)
  linux.device_file = '/dev/input/event7'  (string)
  linux.hotplug_type = 2  (0x2)  (int)
  linux.subsystem = 'input'  (string)
  linux.sysfs_path = '/sys/devices/virtual/rc/rc0/input7/event7'  (string)


Prior to doing that, this is the relevant output in lshal:

udi = '/org/freedesktop/Hal/devices/computer_logicaldev_input_1'
  info.addons.singleton = {'hald-addon-input'} (string list)
  info.capabilities = {'input', 'input.keys', 'button'} (string list)
  info.category = 'input'  (string)
  info.parent = '/org/freedesktop/Hal/devices/computer'  (string)
  info.product = 'i2c IR (Hauppauge WinTV PVR-350'  (string)
  info.subsystem = 'input'  (string)
  info.udi = '/org/freedesktop/Hal/devices/computer_logicaldev_input_1'
 (string)
  input.device = '/dev/input/event3'  (string)
  input.product = 'i2c IR (Hauppauge WinTV PVR-350'  (string)
  input.x11_driver = 'evdev'  (string)
  input.xkb.layout = 'us'  (string)
  input.xkb.model = 'evdev'  (string)
  input.xkb.rules = 'base'  (string)
  input.xkb.variant = ''  (string)
  linux.device_file = '/dev/input/event3'  (string)
  linux.hotplug_type = 2  (0x2)  (int)
  linux.subsystem = 'input'  (string)
  linux.sysfs_path = '/sys/devices/virtual/rc/rc0/input3/event3'  (string)

I restarted the machine to make sure HAL and LIRC reloaded, and my
remote is still behaves as it did before.  I also see this in my xorg

I have tried to modify the xorg.conf file to not have this happen by
adding the following stanza:
Section "InputClass"
  Identifier "Ignore remote IR"
  MatchProduct "i2c IR (Hauppauge WinTV PVR-350"
  MatchIsKeyboard "true"
  Option "Ignore" "true"
EndSection


When I do that, I get no functionality from the remote (i.e., the keys
that did actually work for myth don't and the volume keys do nothing
... I get nothing from any key).  I see this in my xorg log file:
[  1322.226] (II) config/udev: Adding input device i2c IR (Hauppauge
WinTV PVR-350 (/dev/input/event7)
[  1322.226] (**) i2c IR (Hauppauge WinTV PVR-350: Ignoring device
from InputClass "Ignore remote IR"

In each of these cases, I get nothing in my terminal when I run irw
and hit keys.
