Comment 2 for bug 355300

I can confirm this problem; I thought that this was no longer an issue, but it turns out the reason it wasn't manifesting on my T60 was because I had disabled the hotkey-setup init script for testing purposes. :/

Ideally (IMHO), we would be letting userspace handle the mixer entirely, so that the hotkeys, the GNOME mixer, etc. are all interoperating; but I haven't figured out how to accomplish this yet, need to talk to the thinkpad_acpi maintainer about this. In the meantime, we can certainly change hotkey-setup to not propagate these keys to userspace, as a lesser evil.
