Touchpad does not work because of buggy controller implementation of the AUX loop command

SRU justification:

Impact: Laptops touchpads do not get detected and hence do not work if they have a buggy implementation of the AUX loop command.

Fix: see attached patch (backport of upstream commit 1c7827ae70e7c8456e08f7bb9ef2238d27814cbe)

Testcase: With the patch, the AUX IRQ delivery test is bypassed and the touchpad works.

Applied:

http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-karmic.git;a=commit;h=a36ea9e4ead28b3836ba4bd3abaab39fdf16f423

This was in 2.6.32, so its long released for Lucid.

Accepted linux into karmic-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

This bug was fixed in the package linux - 2.6.31-21.59
