FN key to program X keys
It probably won't help, but you could try using a private.xml like this with KeyRemap4MacBook:

&lt;?xml version="1.0"?&gt;
&lt;root&gt;
  &lt;item&gt;
    &lt;name&gt;test&lt;/name&gt;
    &lt;identifier&gt;test&lt;/identifier&gt;
    &lt;autogen&gt;__KeyToKey__ KeyCode::F1, KeyCode::FN&lt;/autogen&gt;
  &lt;/item&gt;
&lt;/root&gt;


See the source for the key code values and predefined settings.
