Dear Maintainer,

this is the first time I install Debian on this machine, so I don't
know if older versions would have worked nor do I know if this is
specific to kfreebsd:

I tried starting X via startx and got a segfault as can be seen in the
log below. Also note the DRM related error message...

If I find the time, I'll try to install again with linux kernel
and followup on this. (Should there be anything more productive
I could do on this, then I'm in for it of course.)

BTW: I read in some other report, that a user had similar problems
that went away when running as root. So I tried running as root,
but still got the segfault it this case.

Dear Maintainer,
*** Please consider answering these questions, where appropriate ***

   * What led up to the situation?
	Upgraded packages this week: xserver and radeon driver for Radeon HD4250

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

	Tried replacing packages (uninstall/reinstall), etc.

   * What was the outcome of this action?
	No change: as soon as I start any application under X, it segfaults with
something like:

	(WW) warning, (EE) error, (NI) not implemented, (??) unknown.

Please don't hijack somebody else's bug.

You can't mix fglrx's libglx.so with the radeon driver.

Cheers,
