Somebody in the thread at some point said:
| Hi!
| Sorry if this has already been solved/discussed before. As people have
| said before, while holding the phone against the ear during a call we
| risk pressing various on-screen keys and do things like ending the
| call.
| Cannot one solution to this simply be to add an "unlock slider" on the
| screen that you need to unlock before you can press any keys? This then
| being enabled when the phone call is answered. Accelerometers can
| perhaps be used to decide when to lock the screen again after having
| pressed the buttons in unlocked state.

I have removed the mokopatch as requested the other day on
stable-tracking now, it should allow an IOCTL to enable and disable
touchscreen traffic as mentioned by Neil Brown:

''All we have to do is undo the kernel hack which effectively disables
EVIOCGRAB and then it is trivial to turn off the touchscreen.
Just open the device and issue that ioctl.''
