I have updated my Ubuntu Oneiric 11.10 kernel PPA with another new experimental patch by Keith Packard[0]. This new patch may resolve the "inverted brightness" and/or the "jumps with successive changes" behavior that has been reported on some systems:
The kernels containing the new patch are tagged "~fix~stuck~backlight4" (use 'uname -a' to check); they will become available within the next day. If you experience any change in your brightness control behavior after updating to this new version, please post a note here.
