Public bug reported:

I can't test/install Feisty Fawn 7.04 Herd 4, when it comes to starting
X it presents black screen, keyboard is functional Ctrl+Alt+F1 gives:
"Ubuntu is loading..." and Ctrl+Alt+F7 gives black screen again.

01:00.0 VGA compatible controller: ATI Technologies Inc Rage 128 PF/PRO
AGP 4x TMDS

So, I suspect this may be a problem: Ubuntu enables DRI by default in 
xorg.conf, it tries to load r128 module but we have this bug open for some time 
now:
https://bugs.freedesktop.org/show_bug.cgi?id=5562

I saw this in Edgy Eft (and Fedora Core 6) too - workaround for
installing it was to replace /etc/X11/xorg.conf with working one that is
different for these lines I need to comment:

#       Load  "glx"
#       Load  "dri"

# Section "DRI"
#       Mode 0666
# EndSection

With Edgy Eft it was different in that way that I had console working,
not with Herd 4 .

One can get Ati Rage 128 DRI working only with this kernel config:

CONFIG_DRM=y
CONFIG_DRM_R128=y

It gives ~ 460 fps in glxgears then.
