Hi Mick,

    I don't think this is possible. I believe persistence was added to 
allow simple system changes and for user data to survive rebooting. 
Kernel upgrades don't work - at least not for me when I tried it.
    On the other hand you might try mounting your usb stick and adding 
your own kernel and initrd to the syslinux directory, but this may take 
a lot of time and still not work. A better solution may be to just 
install a "regular" linux distro onto your usb stick?
