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

After updating to the latest Ubuntu 11.04 beta release at 0900 GMT with kernel 2.6.38-8-generic I got a serious kernel warning / stability message.

This message occurred every time I ran the Ubuntu System Test application. I am running this on a Lenovo X120e with AMD e-350

I have not tried the upstream / mainline kernel (will research how to test that)
