As you can see, essentially what we'd like you to do is to take a look at the Fedora 11 Installation Guide as it currently stands - it's at http://docs.fedoraproject.org/install-guide/ - and try installing either Fedora 11 Beta or current Rawhide according to the instructions found in the Installation Guide.
Should section 7.2 of the install guide have more detail about this feature? https://fedoraproject.org/wiki/Features/NewTextUI
As the developer himself recommends, should users be recommended to try xdriver=vesa before resorting to text mode?
