That card is maybe too new for our old radeon driver.

The Xserver doesn't really a config file these days, but it should work
with the generated one.

You may have the panic message in the output from the kernel messages which you
can get by running /sbin/dmesg

But I suspect you will not see anything because the xserver writes directly
into the memory and if something goes wrong you get the result which you got.

Do you have the drm driver enabled?
Sorry I can not look into my kernel config at home right now to tell you which
option you have to enable while building a new kernel.
