Closing lid results in kernel panic visible on VT-1

The patch had to get reverted as it caused regressions for Intel video
cards (see bug #423296). The problem is that without the KMS code, the
patch just causes the acpi video driver never to get initialized and by
that prevents backlight control. The fix of this bug was unfortunately
just

I've disabled the hack in /etc/init.d/hotkey-setup by commenting out
lines 28-36. After I did that I booted with the new kernel.

Closing lid results
Bah didn't spot that we had a more specific fix for this specific issue.
Seems there are two issues out there. If the first patch does not fix
you then the second test is useful.
For this specific bug it seems that the original fix is good. I will
therefore close this off for Karmic as it is

IMPORTANT:
@Andy, if the more specific fix you refer to is a hotkey-setup change,
that is only a workaround and not a sufficient fix. The kernel should
never panic or hang, no matter what user-mode applications do. If you
pick up the kernel change from comment #32, the hotkey-setup change
should not be

- crash is related to lid event
User-mode code changes are not a fix for a kernel panic, so any hotkey-

As a null-test I've commented out lines 30-34, which contain a
workaround for this bug, in /etc/init.d/hotkey-setup and rebooted to
2.6.28-11-generic, which is currently in jaunty-main. Closing lid caused
a panic again (as expected).
I've installed Andy's amd64 deb's afterwards and rebooted to
