Comment 1 for bug 163432

I also have the exact same symptoms:

01:05.0 VGA compatible controller: ATI Technologies Inc RC410 [Radeon Xpress 200] (prog-if 00 [VGA])
        Subsystem: Intel Corporation Unknown device d600
        Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 21
        Memory at d8000000 (32-bit, prefetchable) [size=128M]
        I/O ports at ee00 [size=256]
        Memory at fdef0000 (32-bit, non-prefetchable) [size=64K]
        [virtual] Expansion ROM at fde00000 [disabled] [size=128K]
        Capabilities: <access denied>

Testing on Fedora Core 7, all packages updated as of 2007-09-20. All gits mentioned updated as of 2007-09-20.

Compiled libdrm and mesa from git and put symlinks (after backing up original files), and also compiled current git for xf86-video-ati . On startup, screen blanks out (LED on monitor turns from green to amber, like a powersaving mode). Keyboard does not respond to Ctrl-Alt-Backspace. Machine is still responsive, since I can ssh from another location and kill X. At least X can return to text mode on kill.
