I am not sure this will ever be fixed. Having 2 drivers for the same
boards should just be a temporary solution. I don't care how radeonhd
and ati get merged in the end,, but the final solution should be a
single driver supporting both the X300 and the HD2600.

What kind of segfault is this? Can you show us the backtrace at the end
of the log?

Multi-board support is somehow broken in current Xserver. Does it work
if you disable the X300 in the config and use ati for the HD2600 board?
If it doesn't work, please try the latest xserver-xorg-video-ati from
experimental, and open another bug report if it still occurs. Make sure
the log from the failure/crash is included in the bug report.

If this segfault is only related to enabling both boards with ati (i.e.
HD2600-only works fine with ati), please open another bug report about
this crash anyway.

This is the log below, right? You should send the log from the failure
with the regular radeonhd and symbol name conflicts for documentation

If ati + non-atombios radeonhd successfully makes both board work,
that's very good news.
