Problem with enable/disable wifi & bluetooth

[PadreSD]

After upgrade to Feisty combination Fn+F5 (enable/disable wifi or bluetooth) on my laptop does'not working.

But, acpi is working.
for wifi:
echo 1 > /sys/bus/pci/drivers/ipw2200/*/rf_kill
echo 0 > /sys/bus/pci/drivers/ipw2200/*/rf_kill

for bluetooth:
echo enable > /proc/acpi/ibm/bluetooth
echo disable > /proc/acpi/ibm/bluetooth

acpi_listen for Fn+F5 show:
ibm/hotkey HKEY 00000080 00001005

please help!!!
