The "fix" has been reverted because it worked by having Linux tell ACPI that it's not a Windows-compatible OS. That can have any number of side effects, and kernel upstream considers it a serious bug to do this.

Upstream work is in progress to expose the BIOS mixer as an ALSA mixer so that we will have OSD notification for this without having to break ACPI handling. Unfortunately this won't be ready for karmic, so 9.10 will have the same behavior as 9.04; but I expect we'll have a solution available in time for lucid.

The mute button not being a toggle is probably not going to be fixed unless the vendor decides to change their BIOS implementation.
