Apple - Media keys behaving like function keys

Ugh. I hate when the solution is "it just stopped happening all of a sudden"... but a firmware update came out and I installed it, and now my keys back! Yay =D

If I learn anything about what exactly happened here I'll post my findings.

tell application "System Preferences"
    reveal anchor "keyboardTab" of pane "com.apple.preference.keyboard"
end tell
tell application "System Events" to tell process "System Preferences"
    click checkbox 1 of tab group 1 of window 1
end tell
quit application "System Preferences"

I have also found one quick fix from here
