Please give a specific example of how you can "instantly and repeatably hang a machine with an ATI video card and DRI". Please give the names and version numbers of your applications that trigger the crash, the ATI video chipset and the ATI Linux driver. I'm calling your bluff because I don't believe it's a generic problem with ATI's Linux drivers. I have had no problems using ATI's Linux driver on a laptop with a ATI Mobility Radeon 9600.

Easy:

1)Install ati's fglrx 3.9.0 on a distro running XFree86-4.3 on a machine with a Radeon 9200 Mobility
2)Start X
3)Start a 2nd X (ie via KDE's "Start new session" menu entry, or via startx -- :1)
4)Change back to the first X instance (ie CTRL-ALT-F7)

Press your reset button, it's the only thing left to do. It works on every machine I've tested it on, without fail.

NVidia has never done this, neither does the open-source radeon driver from XOrg (which also performs just as well on this hardware).

Version 3.9.0 of the fglrx driver is really far too old. You need to get fglrx version 4.3.0 or later. Your example works fine with fglrx-4.3.0 on an ATI Mobility Radeon 9600.
