thinkpad_acpi: WARNING: sysfs attribute hotkey_enable is deprecated and will be removed. Hotkey reporting is always enabled

[free]

Happens on a clean install of Karmic right before I start the first audio test of the systemtest-application.
Btw. when I boot the machine, the ubuntu start sound crackles and lags (like running on a not linear timeline, gets behind and catches up) a bit.
There are many bugreports like this here, but none with exactly my soundcard.
