I could not find anything problematic in the kernel driver.
I have also compared the twl_powerbutton driver but it does nothing obviously
different in its probe() function.
But it appears to be a common problem on ARM-OMAP handhelds:
Maybe we have to dig into the evdev driver source to find out how it detects
if the device is a keyboard or a mouse. Maybe, the gpio-keys driver is too old
to supply some important bit or flag (ioctl?).
