Power button working on iPAQs, using KEY_POWER kernel keycode

Hi,

I got Power button working on h2200.
I think this interests all iPAQs with kernel 2.6 and no working Power button 
till now.

KEY_POWER as kernel keycode.
I use kernel_keymap.patch to Qte, likewise Zauri, for a clean passage of 
keycodes up to Qt level and comfortable definitions of keycodes->key symbol 
mappings.
Mapped to key symbol Hardkey_Suspend (defined as Qt::Key_F34 in odevice.h).
Then in odevice_ipaq.cpp, iPAQ::filter, I intercepted the key and rely on the 
logic already there for Key_SysReq.
So I tested h2200 suspends on short press of Power button; and presumably 
would power off backlight on longer press, if I had appropriate backlight 
code for the machine.

I'll submit pacthes for Opie and OE.
