OK. Might it be better to use an extlinux.conf file? It already has 
support for displaying a menu for all the options in the file, and 
allowing the user to select which to boot. (Although I suspect the 
extlinux.conf menu could be prettied up some). I suppose your example 
above are more than just selecting which kernel to boot though, so 
perhaps extlinux.conf wouldn't work.
