I have no fglrx packages installed, however I purged them to try to get rid of 
possible leftovers. That didn't work.

Then I manually loaded the radeon module using modprobe, expecting some sort 
of error or more clues, but it worked. After this and a kdm restart, 
everything seems back to normal.

For some reason, xorg does not load (or tries to and fails) the readon kernel 
module. I added radeon to /etc/modules so it's loaded at every startup, which 
it does earlier at boot, noticeable due to the smaller console font.

If you consider appropiate, I am willing to do some tests on my machine to 
check why the radeon module is not automatically loaded, but please tell me 
how to proceed (I am almost clueless about kernel whereabouts). If not, for me 
the problem is solved and the bug may be closed.

Thank you for your help :-)
