I compared outputs of lsmod from Ubuntu (3.2.0-25), Fedora (
3.4.2-1.fc16.x86_64) and Debian Wheezy (3.2.0-3-amd64 / Debian
3.2.23-1) and it seems that Debian i915 depends on button.ko, which
depends on ACPI lid button.
I have Fedora and Ubuntu on laptop - they do not have that module
loaded. So their i915 can operate without button.ko.
It's builtin in fedora. I suspect it's the same in ubuntu.
May be it is. May in different way, because:
In Fedora-16 I can use i915 with "acpi=off" passed to kernel, but in Debian Wheezy can't - kernel
unable to load it because there is no acpi and therefor, there won't be lid button.
