I finally have F13 installing from the netinst image on my EEEPC!

I don't think anything I wrote previously is incorrect but I have some
things to add:
- There's no point in copying over the ISO of the netinst image to the
USB disk because it doesn't contain the installer packages.
- Updating the repo= to stage2= is correct but you also have to add
the full path to install.img, i.e:
stage2=hd:UUID=<UUID>:/images/install.img

Bug report[1] with patch has been submitted.
