Hi,

I'm using debian packages from unstable and experimental, my versions are:

kernel: 2.6.22-rc5 #1 PREEMPT Fri Jul 13 22:50:04 CEST 2007 ppc GNU/Linux
xorg: 7.3+3
xserver-xorg-video-ati: 6.7.195-2 

Steps to reproduce the bug:
-Launch the X server
-Execute:  xrandr --verbose --output VGA-0 --mode 1680x1050 --left-of LVDS

X server crash backtrace:

Fatal server error:
Caught signal 11.  Server aborting


Virtual is configured 2704 1050

If I don't put any Virtual statement on the xorg.conf file, the server does not crash, but xrandr cannot set that resolution (because the Virtual screen is too small)

Greetings
