I use a MSI HD4830 on a UP FreeBSD 8.0-CURRENT/amd64 box with

Driver   "radeon"

from ports/xorg-7.4. Without EXA and DRI the graphics card works well,
but when enabling EXA and/or DRI, system goes mustang. Ctrl-Alt-FX
doesn't bring back a console, the tty is 'blinking' as it looks like the
X server tries to start and fails.

On another box, running FreeBSD 8.0-CURRENT/amd64, but SMP and MSI
HD4670, with EXA and DRI enabled the whole box crashes immediately when
loading Xserver. Without EXA and DRI, leaving a windowmaker session and
therefore ending the Xserver kills the box, the OS dies and coredumps or
hangs forever with a tiled screen showing 3 rows of 6 columns of the
console screen on a 20,1 inch TFT.
