@Matt -- that is correct: The 95-keyboard-force-release.rules method is only applicable to 10.04 Beta -- it will not work for previous releases.
Fixing this for 9.10 requires a fix in the kernel itself. I am going to try to extend the in-kernel fix for the Studio 1557 (now pending for release in 9.10) to also work for the Studio 1558.
