How to stop Back on-screen button from vibrating while keeping keyboard vibration?

[NCI]

While I was extremely skeptical of physical keyboard vibration at first, after reflashing the device and typing a bit while having it on I totally love the feature. Vibration after pressing on-screen buttons, however, is something I definitely won't tolerate, it always annoyed the hell out of me. Only one of the on-screen buttons, the Back one, causes this behavior. Is there an option [e.g. some dirty hack] to disable on-screen button vibration while keeping the physical keyboard vibration?

While it may seems weired you will find this settings under Sound->Other Sounds->Vibrate on tap - disable it. IMHO it is independent on the keyboard vibration, that is set elsewhere.
