Comment 19 for bug 220135

Does anyone know why ubuntu's 2.2.0 driver shows the same bug as 2.3.1? Has some buggy stuff been backported? What about upstream's 2.2.0, does that version show the same bug? I'm a bit puzzeled that gutsy's driver was working while hardy's driver isn't, even though it looks like they both are based on the same upstream release (2.2.0).
