Have you tried running the fixvesa command? That should be a first step.
EDIT: I did the searching for you *slaps own wrist*. Here:
Now, for the install.sh script, it calls the Ubiquity installer. The Ubiquity installer requires X to be running. Since your Xserver isn't running, Ubiquity can't launch. Since Ubiquity can't launch, you can't install via the script.Also unless I run "fixvesa" I get "no screens found" error when I run "startx"
