Xorg.log-file of Radeon-Driver

I have a Dell StudioXPS 1640 with an ATI Radeon HD 3670. Unter Ubuntu 12.04, I
was able to use the proprietary fglrx driver. However, since the new
xserver-xorg introduced in Ubuntu 12.10, I am unable to use the proprietary
driver anymore, because ATI stopped support for the graphics card in the newer
fglrx-versions compatible with the new xserver.

I now installed Ubuntu 13.04 and tried to get the radeon open-source driver to
work. When I activate the driver by installing the xserver-xorg-video-radeon
package, the monitor goes dark, flickers once a few seconds later and the
system does not react anymore - the only thing still working is the poweroff
button (no ctrl+alt+backspace, ctrl+alt+del or switching the numlock state
works). I did try several custom xorg.conf files (minimalistic copy of the
fallback with the radeon driver specified, the same with deactivated
acceleration via "NoAccel"-option and a bigger one with specific screen modes,
etc) and the dbus version without any xorg.conf file - all with the same
result. 

The vesa-driver is unable to detect my monitor correctly and leaves me with
1440x960, which is bad for my monitor, because it is not my native resolution
and fuzzy.
I'm now stuck with a generic kernel-mode setting, which has my native
resolution, but is sluggish and unusable.

I've already entered a bug report at launchpad, which has a myriad of files
attached via apport:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1174042

The xorg.log-file does show an EQ overflow at the end, which I do not know how
to handle.
