Issue #2733 has been updated by masu.

File xorg.conf added

After adding "-ht" parameter to ifconfig string I have not seen a 
firmware error anymore, but the X console still freezes when using a 
browser (tried with firefox and midori).

messages contains the following log (starting with drm initialization):

Nov 13 12:24:46 MisterX kernel: info: [drm] Initialized drm 1.1.0 20060810

Nov 13 12:25:39 MisterX syslogd: exiting on signal 15

As you can see in the last log lines, there is still something wrong 
with drm.

Now I thought that this is an xorg issue, searched the Internet for 
fixes and found a few for Linux that modify the "AccelMethod" parameter 
in the graphics card section (change it to "XAA", "EXA", ...). Tried 
them all, but nothing helped.

Hi,

a firmware error of the wifi nic occurrs right after drm is started when starting xserver on my machine.
The nic is automatically reset afterwards and drm becomes initialized.

But then during the X session the nic error occurrs again resulting in an unsuccessful restart that causes also drm to fail which in effect leaves the X console unresponsive.
Strangely this effect appears when browsing the Internet and not when e.g., installing packages from remote locations that also generates network traffic over the wifi nic.

Does someone has a Lenovo X61 and experiences the same problems?

An excerpt from /var/log/messages is attached.

Regards
Matthias
