Comment 70 for bug 446717

When I examined the function key press using logkeys (http://code.google.com/p/logkeys/)
I noticed that a single key press of the Function key alone registers two times.

<E-1d0><E-1d0>

The documentation for the logkeys logfile format, indicates that 1d0 is the keycode in hexadecimal format. Perhaps this registration of this keypress two times is contributing to the error?

Is the patch mentioned by Martin in comment #60 supposed to remove the instability during brightness adjustments? I'm using kernel version 2.6.38-8 and still experiencing the issue.

I am not sure where to check in the /sys or /proc filesystem to determine the number of brightness levels that are supposed to be available to the system, or the current setting.
