I don't think the LEDs are configured in the current kernels:

# cat /boot/config-2.6.18-128.7.1.el5 | grep LED
CONFIG_MAC80211_LEDS=y
# CONFIG_IWLWIFI_LEDS is not set
# CONFIG_IWLAGN_LEDS is not set
# CONFIG_IWL3945_LEDS is not set
# CONFIG_RT2400PCI_LEDS is not set
# CONFIG_RT2500PCI_LEDS is not set
# CONFIG_RT61PCI_LEDS is not set
# CONFIG_RT2500USB_LEDS is not set
# CONFIG_RT73USB_LEDS is not set
CONFIG_USB_LED=m
CONFIG_USB_APPLEDISPLAY=m
# LED devices
CONFIG_NEW_LEDS=y
CONFIG_LEDS_CLASS=y
# LED drivers
# LED Triggers
CONFIG_LEDS_TRIGGERS=y
CONFIG_LEDS_TRIGGER_TIMER=m
CONFIG_LEDS_TRIGGER_IDE_DISK=y
CONFIG_LEDS_TRIGGER_HEARTBEAT=m

Also, you will need the firmware for this device. Both rpmforge and 
elrepo.org have it...

yum install iwl5000-firmware
