Here's dmesg (only listing fglrx lines):

You have another direct rendering module loaded into your kernel (or you
have DRM support for another card compiled directly into your kernel).

cat /proc/dri/0/name

It should list for you the module you have installed.

Something like:

radeon 0xe200 PCI:1:0:0

Then do a 'rmmod radeon' (or whatever module is listed there).

If it says that module isn't loaded, it means that it's compiled
directly into your kernel. You *will* have to recompile the kernel in
that case. If it doesn't give an error message, then it means that that
kernel module is being loaded at some point during the boot process.
You'll have to find out where, and disable it.

Let me know how you make out.
