Gary, then, everything looks good. The quirk for your machine is matched, so that you have /sys/class/backlight/eeepc-wmi directory. And the functions provided by eeepc-wmi are working, so that you can turn on/off your screen by bl_blank.
I need more info to know the problem you have. 1. Does it report any keyevents if using "sudo showkey" and press the display toggle key 2. Which message in the dmesg "Disabling ACPI video driver" or "Backlight controlled by ACPI video driver" 3. Do you have "/sys/class/backlight/acpi_video0/" in your system when using the patched kernel I gave you.
