Subject: evdev regression on macbook with 2.6.33-rc5

Hi,

Since 2.6.33-rc5, the keyboard on my MacBookPro 3,1 stopped working
when using X.
It works fine in console mode, but in X, pressing keys does not have
any effect until I hit the touchpad or an USB mouse and then all the
keystrokes are delivered.
I'm using the nvidia proprietary drivers on Ubuntu 9.10 x86_64
(config.gz and dmesg.gz attached).

A git bisection found this commit as the culprit and reverting it
indeed fixes the problem:

commit 30a589fde0162aa4dac7c69803aeee8fbe8d1b82
Author: Adam Jackson <ajax@...hat.com>
Date:   Tue Jan 5 17:56:04 2010 -0800

    Input: evdev - be less aggressive about sending SIGIO notifies

Thanks.
