[iPAQ] iPAQ kernel death.

The screen is blanked from a timer. h3600_flite_power() uses
interruptible_sleep_on_timeout() to wait for the request to complete.

The kernel promptly dies - "Scheduling in interrupt".

Either h3600_flite_power() needs to busy wait for the response, or it
needs to be called from a kernel thread.

I now have the iPAQ running with the MTD drivers for the flash, and I
should get JFFS working on /usr/local fairly shortly.
