Bug Description
Please add i830 (8086:3577) to the kernel drm KMS blacklist.
Testing has shown that KMS support for the i830 chipset is inadequate, often resulting in a regression where the system hangs during boot up. While the issues have been reported upstream, solutions seem not soon forthcoming. Testers have found that booting with i915.modeset=0 generally tends to restore the system functionality.
[Original Report]
Dell C400 with Intel 82830 CGC, booting
lucid 2.6.32-16-generic causes screen to flash
several times and graphics are then hung
with blank screen and no cursor. No response
to ctrl-alt-F1. Backlight eventually turns off
and then comes back when Shift is pressed.
Remote login with ssh works OK.

Additional info:
1. ctrl-alt-F1 apparently does work, but the screen remains blank. After ctrl-alt-F1, "username\n password\n sudo reboot\n" does cause a reboot. It appears that the system is working, but the screen is displaying black on black after graphics mode is entered.
2. Booting older release 2.6.31-20-generic does succeed in bringing up graphics. I thought that I had tried this release previously, and that it had not worked. I have installed several updates since then.
In summary, in 2.6.32-16 graphics screen goes blank after initial boot messages, but now appears to work OK in 2.6.31-20.
