Too bad... And downgrading to an ATI driver that does support your GPU doesn't work either?
With xorg drivers and mesa when I start nexuiz, I get the black screen, but if I move the mouse to the right or bottom edge I can scroll and surprise surprise there is my desktop. Using xrandr I reset my resolution to 1600x1200 and I get this:

Just wait a few hours

About the hardware accleration needed. OpenGL in software should work just as well (though much slower) as in hardware. OpenGL doesn't even allow for determining whether some function is hardware-accelerated.
Yes, it will work, but you seem to have no idea how increadibly slow mesa software rendering is

Just try to run chromium with software rendering and you'll see...
(It's actually a license problem that mesa software is so slow: it has to be full featured, otherwise they wouldn't be allowed to call it "OpenGL")
