Support for Macbook Air in applesmc

[Henrik Rydberg]

Binary package hint: linux-image-2.6.24-19-generic

The applesmc module wrongly detects the Macbook Air as a macbook, which does
not have keyboard backlights. Also, the sensor set is wrong. A patch is
attached which

1) makes applesmc detect the macbook air

2) sets up a minimal set of sensors

The sensor set is not complete, and the accelerometer is turned off although present, but at least the keyboard backlight
is activated.

A patch against linux-next has been sent to the maintainer, but is awaiting action.

Confirming report, as a patch has been submitted.

Patch is in 2.6.26-5, and works as expected

[Henrik Rydberg (rydberg)]

The v2.6.27-rc4-352-g2085d31 kernel still does not work for the Macbook Air, but this time for a simple reason: the DMI matcher list has the Macbook Air in the wrong place. A patch has been commited.

[Henrik Rydberg (rydberg)]

I am not sure what status the bug should have, given that a fix appeared in 2.6.26-5, which did not fully solve the problem. The following patch was sent to kernel-team a couple of days ago, and takes care of the rest of the problem.

[Henrik Rydberg (rydberg)]

I tested this again today on Ubuntu-2.6.27-3.4, and the problem remains, and the provided patch from 20080905 still applies. It is really a tiny tiny bug which only requires reordering of two list items. Maybe this one was held back by my tagging the bug incorrectly? Please apply, the original problem has had a solution since 20080713 :-)
