Barry, going to ask the hardware chief, but I think it'd be best to turn it into chip RAM by doing a motherboard mod (just cutting a trace and soldering a bridge elsewhere).
It does accept CF cards via a CF adapter. That's why we did put an IDE port there. You can use CF, but also real harddrives. As for autoboot... there's a patch for 1.3 to allow for autobooting, but this hasn't been tested yet.
Not sure if this is the right download, just googled it: http://aminet.net/package/util/boot/kick13scsipatch
