I'm going to change wsdisplay and wskbd for Handheld device's LCD
control. I've made the patch below.
Key points are:
- Add ioctl commands to wsdisplay which set/get some LCD status,
backlight, brightness and contrast.
- Add 9 command key symbols which make wskbd to call wsdisplay's
- Add special key map variant KB_MACHDEP. This variant does not
have any real keymap but it's just a placeholder for machine dependent
maps which will be overwrite by machine dependent keyboard driver.
With this function, you can type Command + Space to turn on/off
backlight of LCD. (NEC MC/R530's keyboard has a space key with
a electric light bulb icon.)
Please check it. If no one have objection to this, I will commit
the patch on next weekend.
