Fedora :: Hotkey : Run Shell Script As Regular User?

I want to run /etc/acpi/actions/blank.sh as a regular user, but it will only run as root. I am trying to setup a keyboard shortcut to run the above script without success. I can run the file blank.sh as root, but not as regular user. Basically I went to: System > Preferences > Keyboard Shortcuts, and added a shortcut to blank the screen. I used the name: Blank Screen, the command: /etc/acpi/actions/blank.sh, and the shortcut: XF86Launch1. XF86Launch1 corresponds to the extra "Access IBM" key found on my keyboard. xev confirms that pressing the "Access IBM" key gives the keycode XF86Launch1. I can launch other programs such as firefox using this method. Here is the actual file blank.sh:

Code:

#!/bin/bash
RADEONTOOL='/usr/sbin/radeontool'
STATUS=`$RADEONTOOL light|awk '/The radeon backlight looks / {print $5}'`;

[code]....

The better method would be to get /etc/acpi/events/blank to accept a hotkey sequence, but this seems broken in Fedora 11. The file blank:

Code:

event=ibm/hotkey HKEY 00000080 00001001
action=/etc/acpi/actions/blank.sh
acpi_listen for keys Fn+F1 reports: ibm/hotkey HKEY 00000080 00001001, but the above file is not being executed.
