Using the radeon driver in "traditional" dual-screen mode (not merged fb), the X server segfaults when the 2nd head is setup to use EXA.

Is this still happening with X.org 7.2, Matthieu?
Sorry about the phenomenal bug spam, guys. Adding xorg-team@ to the QA contact so bugs don't get lost in future.
Things have got worse with ATI driver 6.6.192. See http://bugs.freedesktop.org/show_bug.cgi?id=11852
Fixed in ati 6.9.0 as far as I can tell.
