RE: [iPAQ] blinking square

It means we didn't really shut down much of anything. The new APM emulation
I wrote this week enables us to shut of power to the LCD, FLITE, audio, etc.
when you do a 'shutdown -h'.

There are several interesting power levels we should at least think about
implementing:
        1) active devices turned on, full speed CPU clock
        2) StandbyH: processor clock slowed, LCD off
        3) StandbyL: all peripherals turned off
        4) Suspend: active DRAM flushed to flash or other storage,
           CPU and DRAM halted, all peripherals off
           - requires firmware support, lack of real-time-clock an issue
        5) Off: kernel must reboot

I think we can do (1) and (5) now. I would like us to implement (2) and
(3). I'm not sure (4) is worth the effort -- we'll have to measure power
consumption in the standby states. WinCE gets at least a week of battery
life without implementing 4.
