I can manually control keyboard backlight with
echo 255 > /sys/devices/platform/applesmc.768/leds/smc::kbd_backlight/brightness
to fully turn on or echo 0 to turn it off...  This was after the install of applesmc-dkms.

There does seem to be some oddity traversing the directory structure
there as it seems to loop.

My remaining issue is the ability to adjust this value through the Fn
keys like we can with the display backlight.  Anyone know what is
missing to make that work or a workaround to just send 0 or 255 via
those F5 and F6 keys?

Bug description:
The keyboard backlight on the MacBook 5.1 is not supported as of Jaunty (Ubuntu 9.04) Alpha 5. This is supported in Intrepid (Ubuntu 8.10) by the Mactel PPA packages hal-applesmc, hid-dkms, and possibly nvidia-bl-dkms, though I installed the nvidia-bl-dkms package for Jaunty.
