Bug 757108

Hello.
I am a blind person, and I am using orca screenreader for my computer usage.
The problem is that the orca screenreader cannot be started at the livecd's boot that prevents fedora installation from a livecd without a sighted help.
Because the livecd runs gnome, I could probably press alt+f2 and run orca from the run dialog, but it is not an easiest option.
My proposed solution is to add some boot options and menu entries to allow me to request a screenreader-enabled system bootup.
When I'll request a screenreader-enabled livecd boot, the system should log in and immediately start up a screenreader, namely orca, to allow me to later use the livecd or install the system from it.
It would require autosetting some gsetting keys or something, gnome should carry up the rest, however, I am not really sure what to set cause I still use gnome-2.
Also, in the case of orca bug or something that prevents orca from starting up, there should be a sound at login.
If it'll be the case, then if orca won't be started, I will at least know that I can press alt+f2 and run it manually.
