I just did a quick test run using Grub:

loopback test PATHTOISO
linux (test)/boot/linux26 proxdebug ramdisk_size=16777216 rw
initrd (test)/boot/initrd.img

drops me into the initrd debug shell

if I do the following (major/minor depend on your disk configuration,
  check /sys/class/block/XXX/dev where XXX is your usb partition where
  the iso is)

mknod /tmp/usbdev b MAJOR MINOR
mkdir /tmp/usbmnt
mount /tmp/usbdev /tmp/usbmnt
mount /tmp/usbmnt/PATHTOISO /mnt

followed by lines 294ff of the init script launch the graphical
installer (although the resolution is messed up - probably because I did
not bother to change any of the graphic stuff in Grub), and I am able to
complete the installation..

so I think it must be something in your environment / setup.

(note that there are TWO debug shells, one in the initrd with very
limited commands, and one in the installer environment with access to a
lot more tools - a quick test is to run something like "lsblk", since
that only exists in the latter environment ;). maybe your switch to the
installer environment did not work, and you are still in the initrd
shell? that would explain why you can't execute "xinit")
