Axim has no support yet for LEDs but we already gathered all the hardware
info for that. I'm intending to implement LED support through the input layer
(it supports not only emmiting events but also executing simple commands such
as download effect to joystick, execute effect, light LEDs on keyboards and
such). It would be natural to implement LED support inside the button
driver, as if the LEDs would be keyboard LEDs.

Look in aximx5_buttons.c, it's pretty simple. However, I haven't found yet a
way to make it useable, since the applications ignore the scancodes it emmits
(such as KEY_CALENDAR and such). I think the applications have to be modified
to support these keys.

sysfs definitely. It already should work for h2200.

For suspend you must first find a suitable bootloader.

Yes, it already works. Look at aximx5_battery.c for example.
